My musing in the above thread was apparently incorrect. This
has nothing to do with my buggy fifo implementation. I did a little
more checking on this and the problem is that something like this
doesn't work right now in cygwin:
echo hello >/proc/self/fd/1
when it should. Implementing this isn't too tricky. However,
implementing the more general:
echo hello >/proc/<some-other-pid>/fd/1
is harder.
