problem: occasional keystroke doubling (a known issue?)

[Lev Bishop]

Well, it looks like while I was composing that message there were people 
solving the same problem. How nice that the cygwin/xfree86 community is so 
responsive as to be able to post me fixes before I've even finished 
posting the problem report ;-)

Anyway, "xset r off" does, indeed, seem to fix my problems, and even 
without turning off autorepeat (which is presumably handled by windows 
independently).

Great.
