[issue7341] test_tarfile failing (file in use when deleting) on Windows buildbots

[Paul Moore]

New submission from Paul Moore <p.f.moore at gmail.com>:

Windows 3.x buildbots are failing in test_tarfile.

The problem, as best I can diagnose it, appears to be a failure
somewhere in the tarfile module to close files on exceptions. The error
is "WindowsError: [Error 32] The process cannot access the file because
it is being used by another process", but I am pretty sure it's actually
the *same* process which still has an open handle on the file. The
problem occurs around  test_append_gz, which tries to open the tarfile
but expects an error. I think when the call raises the error, it is
leaving a filehandle open, which is what causes the delete in setUp to fail.
