Any chance you could bisect Cygwin to help finding the culprit?

The culprit is

commit 252a07b0ad3353abcd0fcd9b1b65ff977acd679e
Author: Takashi Yano <>
Date:   Fri Apr 3 13:07:35 2015 +0900

   Cygwin hangs up if several keys are typed during outputting a lot of

       * (fhandler_pty_slave::read): Change calculation of
       "readlen" not to use "bytes_in_pipe" value directly.

Reverting that commit fixes the problem.

Unfortunately, all kinds of other things break.  For example, emacs exits
immediately, ls produces no output,....

Are you sure?  I just tried it myself and ls as well as emacs work
fine for me.

It works for me now too. I must have done something wrong the first time I tried.

Thanks for rechecking.
