Sure. I think this is PEP material - I would like to declare
"expected failure" as well.

That would be fine (of course, we move away from SF, so these method
names, at some point, will trigger synapses only for old-timers
that still remember sourceforge; the bug IDs will remain constant in
the next tracker).

The error Windows reports is ERROR_SHARING_VIOLATION. I never
understood sharing fully, but it may be that if the file is opened
in "exclusive sharing", stat'ing it may fail.

I personally consider it a bug in Windows that you cannot get file
attributes if some other process has opened it. Exclusive access
should only restrict access to file contents, but not file attributes.
