Most odd. Anyway, I'm far more comfortable hacking Python than I am Cygwin, so 
I'll get back to the list once I've taken some more time to dig into the guts of 
the failing test.

For the pipe-handling issue, I take the fact that Python's test_subprocess 
passed as a very good sign, since I understand that uses pipes for its 
inter-process communication.
