I see that your patch makes writepipe_exists non-inheritable. This
means that if you pass a pipe to a windows process, which in turn
passes it to another process, the writepipe_exists will be gone, and
cygwin will think the pipe is closed, AFAICT. So something like:
bash$ ls | cmd /c more
will not work any more. I think... I can't check this, because I don't
have access to old versions of windows where writepipe_exists is
actually used.
