939606 - Run GC and CC more aggressively during mochitests

Status: RESOLVED DUPLICATE of bug 949607

(Core :: JavaScript Engine, defect)

Description

[Andrew McCreight [:mccr8]]

billm suggested that we could schedule additional slices of GC during mochitests.  This could be done after every test, or we could reduce the GC/CC timers.  The latter is a little more risky, because we're changing behavior, but maybe it isn't so bad.  The problem with the former is that this could do weird things with CC scheduling: we want the CC to run more, too.

That's a little different.  The code there right now forces full GCs and CCs after each test, but billm pointed out that's bad because we end up not really running ICC.  In that bug, smaug is looking at changing it so we only do forced GCs and CCs after shutdown, which will help with running OOM during shutdown, but it would still be nice to reduce memory usage during a run.
