Yeah, I saw that change, and I tried yesterdays snapshot but it still
hung. I also did some more googling and found that someone submitted
a patch a few years ago. The patch checked to see if it was inside
the ntdll.dll by looking at the handle.

I found this google too. http://blogs.msdn.com/oldnewthing/archive/2004/01/28/63880.aspx
I'm going to try that patch today and see what happens. Christopher
didn't apply it because it was a bandage and didn't really fix the
bigger problem.
I tried putting the patch in place, and it stopped hanging at the place I reported. I had print statements to verify that it went through the section. However, the program still hung at some point. I tracked down a couple of other GMFN calls that used non-null handles and tried using the technique that the patch had.
Does the latest snapshot behave any differently? It has a temporary
patch which stops cygwin from suspending (for long) when the current IP
is in the cygwin DLL itself.
