Guy, do you have an environment where this is still happening and
where you could test a potential fix? We are not sure yet what's
causing that, but one code path has changed in this area, involving
CreateHardLinkA()+_unlink() instead of a single rename when attempting
to recycle a segment. And I am just in a mood to build things by
myself and send some links to people to be able to download and test
that, so one more is fine..
