Cygwin's setlocale function only supports the "C" locale.
I am a bit suprised that ASCII is returned rather than the system's default 
encoding.
(I believe that should be Latin-1 on my system).

Good guesses, but the indexing service is turned off, and I am not running 
any virus scanning software.

The failures for the 2.5 test come from lines that look like:
"for line in f:". The failures in the 3k tests come from the lines that 
attempt to open the file.

It does seem likely though that something is going wrong with the deletion, 
effectively delaying
it, which is triggering the errors. But i'm not sure what.


But actually looking closely I was mistaken. Only one test failed under 2.5. 
That was TestMH's test_pack.
It may be a fluke. Or perhaps the Cygwin Python maintainer understood that 
failure and decided it was nothing to worry about.

GvR's thoughts of changing file permissions do not seem to work, as test_add 
certainly does not look to be changing file permissions.
