[Python-Dev] backporting stdlib 2.7.x from pypy to cpython

[Matti Picus]

The windows port of pypy makes special demands on stdlib, specifically that 
files are explicitly closed. There are some other minor issues, in order to
merge all the changes necessary to get pypy windows up to speed, around 10
modules or at  least their tests seem to need to be modified.
I have been doing a bit of work on the stdlib shipped with pypy 1.9 
(version 2.7.2 unfortunately) to make it compliant. Assuming there is interest, 
what would be the best path to get, for instance, a modified version of 
mailbox.py with its tests (test_mailbox.py and test_old_mailbox.py) backported
to cpython?

PS - I know closing files on delete is also an issue for cpython3.3, I did
merge as much of 3.3 back into mailbox as I could, but there were still more
issues.
