The bottom halves API is not thread safe, but calling
qemu_bh_schedule_idle()
Not _idle please.
in another thread *seems* to be safe (here, it
would be protected from qemu_bh_delete() by vnc_lock_output()).
If it weren't protected against qemu_bh_delete, you would have already
the same race between writing to the socket and closing it in another
thread.
