I think the problem is present when there was *no* conflict
previously. Because nothing populates the stats entry without an error, the
reset doesn't have anything to set the stats_reset field in, which then means
that the stats_reset field is NULL even though stats have been reset.

I'll just repeat what I've said before: Making variable numbered stats
individiually resettable is a bad idea.
