Why not try to debug it your self?

Have you tried to strace it?

Can you get a stack trace of the hang in gdb?  Note: You may need a debug
version of the cygwin1.dll or shell for this to be valid.  I will provide
the former if you are willing to test it.

Yes.  A bugzilla style database has been proposed, but we have not found
anyone willing to maintain it yet.  Want to volunteer?
