test_bz2 currently uses the test.support.TESTFN functionality which creates a temporary file local to the test directory named around the pid. This can give rise to race conditions where tests are competing with each other to delete and recreate the file. This change converts the tests to use tempfile.mkstemp which gives a different file every time from the system's temp area

LGTM. As an approach, this seems fine, although it's possible that a test that expects the file to not exist in advance could fail if changed to use this approach. That would be fairly easy to spot and fix on a case by case basis, though.
