Copying from the upstream bug as I'd need some advice on bsd
glibc. We're looking for explanation for this behaviour.

====
I the following patch fixes the problem for me (as well does reverting from
recv to read. I'll see if I can work out why it fails here without the patch
with debian-bsd at lists.debian.org folks.

recv seems to fail (loop) with "Resource temporarily unavailable" (ret=-1,
errno=35) according to ktrace
