I think it'll work; it falls back to _get_osfhandle, So if you can
WaitForMultipleObjects on the Windows pipe handle, it'll do OK. It
was just for some serial cases where you needed a separate handle that
we had problems. OTOH if waiting for the pipe handle means you can
connect to it, or some other interpretation, we'll be back to the
beginning. You could maybe adapt ser-pipe.
