This sounds very much like it _may_ be the same problem as discussed
(at inconclusive length, sorry!) wrt xemacs in this thread:

  http://lists.xemacs.org/pipermail/xemacs-beta/2014-January/024736.html

I've burned a lot of midnight oil on that one, with no real joy as
yet.

At the very least it does seem like there was some change in
Cygwin pty/signal area some time back which affects the way emacsen
try to communicate with sub-processes. . .
