Hi all,
I've noticed that once an IRDA socket is in accept(), any further action that requires locking the
socket will result in a hang until accept() is completed (which may take a while). After a while
hung task spew is printed out.

listen(sock) |
bind(sock) |
accept(sock) |
| setsockopt(sock)
*HANG*
I'm not sure I can provide a properly tested fix since I don't actually have IRDA hardware to test
on.
Thanks,
Sasha
