Ahh, and then later that is removed, but when it is removed it also
remote the wakeup before the pipe_wait(). So whatever issue that
commit introduces ends up remaining.

I wonder if the extra wakeups ended up hiding some other bug. We do
extra wakeups on the write side too, with a "FIXME! Is this really
true?" comment..
