I worked on this for a long time since trying vista and here's my solution CYGWIN=title server itty binmode glob tty
I believe that some arrangement of CYGWIN args cause troubles, but I can't verify which, and I also believe I had ntsec in there before. It would run for a while, althouhg process explorer would show 9-10 thousand context switches per second for XWin.exe, then eventually it would go to XWin.exe running full blast an unresponsive until I killed it.
