Debugger should provide an API for analyzing heap usage and catching leaks. This should include: - ways to find paths by which objects are retained - ways to compute objects' retained sizes, and identify the largest N objects in each category - ways to take a census of the heap and count the numbers (and sizes) of objects in various categories - ways to take complete, serializable snapshots of the heap, and examine them (almost) as if they were live.
There is IterateZonesCompartmentsArenasCells(), which lets you iterate over the heap. It could be the basis for the 3rd and 4th items in comment 0. The 1st and 2nd items in that comment will need something more like JSTracer.
