[Message part 1 (text/plain, inline)]
Patch attached.

It's possible this'll livelock certain glib libraries that want to
modify the glib main context while another thread is running. I don't
see a good way to fix that, but a bad way would be to apply some
heuristic (such as a 10 ms delay between calling select() and assuming
it actually was called).
