Looks like there's some other problem with AF_UNIX on OS X that nobody
has reported so far :-(

Is there an OS X equivalent of strace that you can try running it under?
I'd be interested to see what that too-long name actually is.

It doesn't, but the problem is that if something with the same
observable behaviour as /dev/null gets registered for polling by the
main loop, poll() immediately returns (with the "invalid" flag set for
that file descriptor), so it's very easy to get a busy-loop.

On the other hand, I added code for
https://bugs.freedesktop.org/show_bug.cgi?id=23194 and
https://bugs.freedesktop.org/show_bug.cgi?id=32992 (both in 2011) which
should avoid busy-looping.
