Try capturing stderr, and see what's there.  I suspect you may be
getting an error message like this:

  52967 [main] python 9340 C:\cygwin-1.7\bin\python.exe: *** fatal error
- unable to remap \\?\C:\cygwin-1.7\lib\python2.6\lib-dynload\time.dll
to same address as parent: 0x360000 != 0x3A0000

Perhaps running rebaseall (or some analog to perlrebase for python?)
