[Python-3000] Need help with Windows failures

[Guido van Rossum]

Hi Christian and Amaury (and anyone else with a Windows setup who
would like to help!),

I noticed that both of you are contributing fixes for Windows-specific
issues. Could I get your help with some other Windows issues?

See e.g. the failures on
http://www.python.org/dev/buildbot/3.0/x86%20XP-3%203.0/builds/182/step-test/0

I'd be happy to give you some pointers on specific failures if you
can't figure out what might cause them. (To find the errors, scroll to
the end and then scroll up; or search for "Re-running failed tests in
verbose mode".) Please CC Neal Norwitz as well, he may have some
suggestions as well.

Some random notes:

- It looks like there are some CRLF issues. Quite a few things
complain about mysterious syntax errors; I see some problems where \n
characters seem to appear or disappear.

- Most of the mailbox test failures seem due to a failed cleanup in
the second failing test (note how it prints FAIL and then ERROR --
that suggests the ERROR happened in the tearDown()).

- In general, whenever you see other failures mentioning things like
"The process cannot access the file because it is being used by
another process: '@test'" it's probably a failed test not properly
cleaning up; a lot of tests either don't always close files (could use
try/finally: f.close()) or don't remove them. (The best way to remove
files btw is typically test_support.remove().)

Thanks in advance to anyone who fixes a Windows bug in Py3k!
