Hmm, I can reproduce this even with stty -echo.  The tty code is not
exactly my domain, so I'm not sure at the moment where to look.  I guess
the locking strategy in the tty code is not robust enough.  Did you have
a look into the cygwin sources in the meantime, by any chance?

Since this is not a regression from 1.7.34, I'll defer this problem
until after the 1.7.35 release.
