make-network-process calls getaddrinfo and C-g doesn't work properly
during that call.  It's only observable if the name server is slow or
misconfigured.

glibc has a asynchronous variant getaddrinfo_a (in libanl.so) which uses
threads internally and quickly passes control back to the caller.  That
could be used on GNU/Linux but the OP uses a Mac.
