quickly, but the other could always fail or timeout (when we are
talking to a pool of DNS servers that can only successfully resolve
IPv4 address, for example).
it is 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 do not want to wait _too_ long or users will think
requests are slow when IPv6 lookups do not 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 did not 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 cannot know exactly
where in its retry cycle we are. We could guess based on how much
time has gone by, but it does not really matter. Happy Eyeballs tells
us that, given usable information in hand, we simply do not 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 do not even know where in the
c-ares retry cycle each request is.

* There is nearly no exception to above rule. All libcurl source

* 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.
