+         talking to a pool of DNS servers that can only successfully resolve
+         IPv4 address, for example).
+
+         It's also possible that the other request could always just take
+         longer because it needs more time or only the second DNS server can
+         fulfill it successfully.  But, to align with the philosophy of Happy
+         Eyeballs, we don't want to wait _too_ long or users will think
+         requests are slow when IPv6 lookups don't actually work (but IPv4 ones
+         do).
+
+         So, now that we have a usable answer (some IPv4 addresses, some IPv6
+         addresses, or "no such domain"), we start a timeout for the remaining
+         pending responses.  Even though it is typical that this resolved
+         request came back quickly, that needn't be the case.  It might be that
+         this completing request didn't get a result from the first DNS server
+         or even the first round of the whole DNS server pool.  So it could
+         already be quite some time after we issued the DNS queries in the
+         first place.  Without modifying c-ares, we can't know exactly where in
+         its retry cycle we are.  We could guess based on how much time has
+         gone by, but it doesn't really matter.  Happy Eyeballs tells us that,
+         given usable information in hand, we simply don't want to wait "too
+         much longer" after we get a result.
+
+         We simply wait an additional amount of time equal to the default
+         c-ares query timeout.  That is enough time for a typical parallel
+         response to arrive without being "too long".  Even on a network
+         where one of the two types of queries is failing or timing out
+         constantly, this will usually mean we wait a total of the default
+         c-ares timeout (5 seconds) plus the round trip time for the successful
+         request, which seems bearable.  The downside is that c-ares might race
+         with us to issue one more retry just before we give up, but it seems
+         better to "waste" that request instead of trying to guess the perfect
+         timeout to prevent it.  After all, we don't even know where in the
+         c-ares retry cycle each request is.

+ * Nasty internal details ahead...
+ *
+ * File curl_memory.h must be included by _all_ *.c source files
+ * that use memory related functions strdup, malloc, calloc, realloc
+ * or free, and given source file is used to build libcurl library.
+ * It should be included immediately before memdebug.h as the last files
+ * included to avoid undesired interaction with other memory function
+ * headers in dependent libraries.
+ *
+ * There is nearly no exception to above rule. All libcurl source
+ * files in 'lib' subdirectory as well as those living deep inside
+ * 'packages' subdirectories and linked together in order to build
+ * libcurl library shall follow it.
+ *
+ * File lib/strdup.c is an exception, given that it provides a strdup
+ * clone implementation while using malloc. Extra care needed inside
+ * this one.
+ *
+ * The need for curl_memory.h inclusion is due to libcurl's feature
+ * of allowing library user to provide memory replacement functions,
+ * memory callbacks, at runtime with curl_global_init_mem()
+ *
+ * Any *.c source file used to build libcurl library that does not
+ * include curl_memory.h and uses any memory function of the five
+ * mentioned above will compile without any indication, but it will
+ * trigger weird memory related issues at runtime.
+ *
+ * OTOH some source files from 'lib' subdirectory may additionally be
+ * used directly as source code when using some curlx_ functions by
+ * third party programs that don't even use libcurl at all. When using
+ * these source files in this way it is necessary these are compiled
+ * with CURLX_NO_MEMORY_CALLBACKS defined, in order to ensure that no
+ * attempt of calling libcurl's memory callbacks is done from code
+ * which can not use this machinery.
+ *
+ * Notice that libcurl's 'memory tracking' system works chaining into
+ * the memory callback machinery. This implies that when compiling
+ * 'lib' source files with CURLX_NO_MEMORY_CALLBACKS defined this file
+ * disengages usage of libcurl's 'memory tracking' system, defining
+ * MEMDEBUG_NODEFINES and overriding CURLDEBUG purpose.
+ *
+ * CURLX_NO_MEMORY_CALLBACKS takes precedence over CURLDEBUG. This is
+ * done in order to allow building a 'memory tracking' enabled libcurl
+ * and at the same time allow building programs which do not use it.
+ *
+ * Programs and libraries in 'tests' subdirectories have specific
+ * purposes and needs, and as such each one will use whatever fits
+ * best, depending additionally whether it links with libcurl or not.
+ *
+ * Caveat emptor. Proper curlx_* separation is a work in progress
+ * the same as CURLX_NO_MEMORY_CALLBACKS usage, some adjustments may
+ * still be required. IOW don't use them yet, there are sharp edges.
