I kinda suspect that what you are looking at is a problem with the
delayed-unlinking feature that we built to cope with Windows' inability
to unlink open files, ie, it's being a little too slow to do the
unlinks.  Would you refresh my memory about exactly where and when the
unlink happens if the initial try fails?
