I've actually coded a solution to this, and I used option a because I
only have to do the search once, and I can keep accurate numbers after
that.  Basically, you need to go into objsave.c and when a new user comes
into the game, SUBTRACT one instance of the object as it is being created,
because the creation routine will add one back in.  When a player exits
the game, ADD one instance of the object, since the purge routine subtracts
one.  All the numbers will end up balancing fine, and will only change if
someone junks something, a zone resets, a God creates a new item, a shop
produces something, or create food gets cast (there's probably more).  The
best part is that this technique only modifies the code in 3 places, and
the rest work fine.

I'll be submitting my code to Jeremy for version 3.1, because I don't
want to slow down 3.0 production.  I think the code is really useful
because players can't race to mobs to find maxxed out equipment after
a crash... because it won't be there.
