I think this is because of this longstanding cygwin issue:
http://cygwin.com/ml/cygwin-patches/2003-q4/msg00055.html

Which I think may also be the reason why it usually makes my console
unusable if I try to use  ^Z to suspend, eg,
$ yes | less

(Although I haven't looked at this stuff in ages, so maybe I don't
know what I'm talking about -- I'm sure CGF will pipe up if I'm
completely wrong).
