Congratulations and thanks to Chad Mynhier for a substantial contribution
to DTrace! Chad has fixed a couple of bugs and added a standard deviation
aggregation action.
Chad, nice work; now how about an update to the wiki for stddev()? :-)

6325485 A stddev() aggregator would be a nice adjunct to avg()
6618705 p*d123 doesn''t cause pid probes to be created
