getaddrinfo() has worked fine here for several months, though I have
only used it in single threaded programs, and its not stressed in the
apps I've used it it.
As to whether its thread-safe, from src/lib/libc/net/getaddrinfo.c:
" Issues to be discussed:
- Thread safe-ness must be checked."

" Note:
- We use getipnodebyname() just for thread-safeness. There's no intent
to let it do PF_UNSPEC (actually we never pass PF_UNSPEC to
getipnodebyname()."
