Thanks. I've raised a bug report for this. Unfortunately I can't see
what's causing this just now... My best guess is that there's a missed
ns_send_appdefined somewhere. Can you switch to the thread that's
running fd_handler and see what it's doing? There are only two
branches, so it should be easy to work out which one is in use.
