This sounds great, would probably catch most of the cases I´m thinking
about without having to reach outside the cache that often.

On a related note, looking at the code it seems to me that getaddrinfo
holds a mutex while it´s waiting for get lookup to complete so if there
is a stalled DNS lookup all other threads wait on the mutex? Is this
observation correct?
