I'm not fully clear about your suggestion about upping the timeout. Currently
our app only talks to one host only so yes, generally upping the timeout would
be a sensible thing to do. However I would expect to see a gethostbyname call
every 60 seconds by default but it sometimes takes longer when requests are
going out back to back.
Can this have something to do with cached connections, as if there is a match
for a given hostname/port and the connection is considering to be good no name
lookup is attempted despite the fact the corresponding DNS cache entry is
technically stale per configured CURLOPT_DNS_CACHE_TIMEOUT value?
