[PATCH] Fix a race condition in pty.c
There is a race condition int pty.c when pty_close wakes up waiter on its
pair device before set TTY_OTHER_CLOSED flag.
It is possible on SMP or preempt kernel, waiter wakes up too early that it
will not get TTY_OTHER_CLOSED flag then fall into sleep again - missed wakeup.
hjl reports that this bug will hang some expect scripts on SMP machines.
