I should have stripped that out, but my patch would result in lock
order reversal between a socket lock and a process lock.  As we
protect p_fd by a process lock, we have to lock it prior to locking a
file descriptor or a socket.

I suppose I have to commit the stripped patch of a sigio lock first.

Speaking of the sigio lock, is that likely to apply to a pipe as well?
