--- Comment #20 from James E. King, III <jim.king at simplivity dot com> ---
I can also confirm that we were able to reproduce this issue easily and once
the patch was applied, we were not able to reproduce it easily any more.  It
can show up in a core looking like
https://sourceware.org/bugzilla/show_bug.cgi?id=12926 with a hang in check_pf
holding a lock, and all other threads calling getaddrinfo() are blocked waiting
for a reply that may never happen.
