This should have been fixed by bug 688292, which fixed a memory usage spike in chrome-intensive workloads where jitcode was not getting released fast enough (a pseudo-leak).  Graphs 9/24 and later look similar to the 9/19 ones, e.g. Windows:

Confirmed memory usage has dropped back to pre-regression values from build 20110923030857.
