I'm testing.  It looks good so far, but I'd like to get emacs running 
without a crash for 24 hours before I'm confident.  I'll report back 
tomorrow.

I'm also testing to see if the recent changes have fixed the problem 
that I was struggling with in 
http://cygwin.com/ml/cygwin-xfree/2012-04/msg00048.html .  That also 
looks good so far.
