Concur - it's never worked AFAIK. Not that you need my concurrence, since
you're the developer in the best position to know.

Are you really sure it ever worked? To the best of my knowledge the
control master stuff always required descriptor passing via AF_LOCAL
sockets, which is not available under Cygwin.

Did notice that the "uname" information you provided is the same in the
working and failure cases? Maybe you pasted the wrong results in one case?
