Igor landed a patch that regressed the leaks a bit.  See {{bug|375808}}

We're still missing javascript edges and that might cause leaks of windows.  Igor has been working on a patch that makes the GC code and traversal code share the same code.  So we automatically find all the javascript edges.

* {{bug|375063}} (Leaking nsJSContexts and nsXBLDocGlobalObjects at shutdown):  This is the bug that caused Igor to write the {{bug|375808}}.
* {{bug|375063}} (Leaking nsJSContexts and nsXBLDocGlobalObjects at shutdown):  This is the bug that caused Igor to file {{bug|375270}}. Will probably want to fix {{bug|375270}} instead of landing the fix for {{bug|375063}}.

Tried to reland patch for {{bug|372960}} (Make XPConnect traverse more JS edges), but Tinderbox is still going orange. Will probably back out again, seems related to CC performance issue. Tried to turn on jst's timing code, but that made Tinderbox go green so can't debug the issue then.
Made new patch for {{bug|372713}} (Add cycle collection to RDF datasources) to address r- comments.


These are a bunch of safety checks that need to be removed in order to improve the performance:  {{bug|373693}} (Cycle collector makes AddRef about 6x slower) and {{bug|373694}} (Cycle collector makes Release about 11x slower), not done yet.
