I don't know.

AFAICT, no.
However, another threaded regression test hung in 1.5.12 as indicated in
the README:
Under XP Pro SP1, Cygwin 1.5.12-1, ntsec, and NTFS, Cygwin Python
passes all tests except for following:
...
test_threaded_import (occasionally hangs)
So, maybe I was just "lucky" test_threadedtempfile did not hang when I
ran the regression test especially since it hung under 1.5.10-3.
