Read the kstat variables of interest as soon as your process starts,
and use that as the 'zero' reference point. Subtract to get the delta
since program start.
We don't provide a way to reset the kstat values for at least three
reasons:
1. It would be destructive. Clearing out the kstats would affect
*all* consumers, and not just the individual process or user
currently reading them.
2. It would violate SNMP semantics. Counters are not permitted to
roll backwards without an engine restart.
3. Using simple arithmetic to arrive at interval deltas is simpler
and more effective anyway, so there's just no need.
