The issue was that Python unconditionally changed the behaviour of the 
CRT, not only during the test suite.  I'm inclined to agree that Python 
itself (ie, pythonxx.dll on windows) has no business changing these 
flags, but it should be up to the application - ie, either python.exe 
itself, or exposed to the python app - the latter of which is what my 
patch offers.  Note however that my patch doesn't cause any .py code to 
actually change the flags, just offers the ability for them to do so.

Curt's suggestion of redirecting to a file is better still - I'll look 
at tweaking my patch to also offer that capability...

Cheers,
