Clayton put that in looking forward to a time when innd would be
multithreaded.  That sequence shouldn't be hit in normal usage in the
current inn environment, as it should only hit when the cache is full
and all the cached groups are ones that have been OVopengroup()ed and
not OVclosegroup()ed, as OVopengroup ups the refcount and OVclosegroup
decrements the refcount for each group.  In other words, you should only
be seeing this if the code elsewhere is sloppy and failing to clean up after
itself by OVclosegroup()ing what it OVopengroup()s.
