----------------
Yea, a lazily constructed index seems like it would be a good idea.  For those dumps which don't contain full heap information this will probably be pretty quick, but if a dump has full heap information this is going to be a huge slowdown.

Not something we have to worry about right now, but we'll need to address it eventually.
