Hi,
I'm trying to figure out the interactions between rusage and pthreads. Peeking
around in the kernel (7.2) I see updates occurring in various places.
kern_clock.c, for instance, appears to increment the memory occupancy (*rss)
counters. This would make it appear that every thread gets

Chuck,
I forgot to add:
Nope. statclock() is fired off periodically (with
some fuzz, to avoid clever games by processes trying to
avoid being sampled) to update the stats for the currently
running process.
Which would mean that a process that is occupying memory but doesn't happen to
be

This looks to me like it's accumulating the data in per-thread
