The problem is that GetOpenFileName and GetSaveFileName did not release the GIL.  I've checked a fix into CVS, but unfortunately I'm not sure that helps you.  Contact me offline if you would like a new win32gui (also let me know which python version you use).  Also let me know if you would like a beta-tester for any mercurial extensions you may be developing ;)
