bq. From the doc: Neither DescriptiveStatistics nor SummaryStatistics is
thread-safe.
Thanks, originally I had synchronized blocks around the updates but removed
them. Seems the version of the patch I put up is missing that todo, sorry about
that.
bq. Last time, I checked DescriptiveStats, I remember being concerned about
it's performance.
Yeah, so then I'm going to remove the fix versions and just leave this hanging
around, because I can see this is going to be more involved than I want to
invest time in.
Thanks for taking a look. Maybe someday I'll redo this with threadsafe stats.
Edit: Hit save too soon.
