> prePut coprocessor hook causing substantial CPU usage

> I was running an insert workload against trunk under oprofile and saw that a
> significant portion of CPU usage was going to calling the "prePut"
> coprocessor hook inside doMiniBatchPut, even though I don't have any
> coprocessors installed. I ran a million-row insert and collected CPU time
> spent in the RS after commenting out the preput hook, and found CPU usage
> reduced by 33%.
