Subject: shutdown(3) and bluetooth.

Is shutdown() allowed to block indefinitely ? The man page doesn't say either way,
and I've noticed that my fuzz tester occasionally hangs for days spinning in bt_sock_wait_state()

Is there something I should be doing to guarantee that this operation
will either time out, or return instantly ?

In this specific case, I doubt anything is on the "sender" end of the socket, so
it's going to be waiting forever for a state change that won't arrive.

	Dave
