The about:memory log in bug 975702 shows 1.5MB of empty cells in non-empty arenas, which is quite a bit. It would be cool if we modified DumpHeapComplete to include information about the number of empty cells in each arena that we log, and hopefully that wouldn't be too hard. That might make it easier to identify what is happening.

In addition to being nice for manual poking around it would also enable the development of analysis scripts for internal fragmentation.
