I didn't phrase my comment somewhere about "future snapshot TBA" as I had 
intended.  I just meant some future snapshot, not that I was requesting one for 
this patch.  But thank you very much anyway.  I'll sort out with Marco whether the 
Python end of the OP's issue patch should go into pythonX.X-test or pythonX.X 
itself, separately.  BTW The whole set of Python tests might serve to test Cygwin 
in a manner we haven't seen|used yet...
Cheers,
