Hmm. That would also be a bit off, imo. A better solution would
be to write the file directly to the check_result_path and then
just create the .ok file when checking is done. In that case, we
won't need to worry about cross-filesystem renames (which are
expensive since they always incur 4 disk-seeks and one memcopy).
Granted, the two of the seeks should always be cached, but it's
still 2 cold ones we can avoid entirely.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
