counter roll-overs.  With 32 bit counters, you will have frequent
rollovers.  Now try to do math on two sets of rolling counters - there
is no way to determine if they have rolled or not.

The best way to deal with this is to use rrdtool as the backend, and
routers2.cgi as the front end, and do the math on the two RRDs, rather
than the raw counters.
