> Using the build dated 29 Nov 09, the output from "nodeprobe tpstats" is
> confusing. The following observations were made with an idle server that was
> compacting to clean up after some writes that were done in the past. The
> number of pending tasks for COMPACTION-POOL starts at 1673, and after doing
> some work the number of pending tasks has increased to 1675. I'd prefer that
> the amount of pending work reported by tpstats decreases as work is done.
