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.
