I'm sorry, but somehow I could not parse this. My understanding was that the unittest was meant to make sure an os.stat call would be successful on an open file, and that pagefile.sys was simply used as a known open file, which is no longer correct.

No. The unit test was meant to test that os.stat is successful on an open file on which 2.5 reported ERROR_SHARING_VIOLATION. I believe it was not the case that it would report ERROR_SHARING_VIOLATION when stat'ing arbitrary open files, but just open files where some additional conditions must be met. I might be misremembering - I think I tried to write the test case just like you did, and it could not trigger the bug. I then concluded that I could not figure out what these additional conditions were, and that it had to be the pagefile.

So please verify that your new test indeed breaks on 2.5.0 (or undo r54686).

Regards, Martin
