<pre>Currently, I'm trying to track the lifetime of a particular object. I want to find out if it was collected between GCs. I have no way of finding this information out now. It'd be very nice to be able to ask some questions about a particular object:
1. Did it ever get deleted?
2. Between which two snapshots was it deleted?
Also, it could be neat to switch to a view where deletions are part of heap snapshot diffs. This would help me out a lot.
Currently, it's very hard to tell if an object is still alive because it's impossible to track all the paths to an object, so it's hard to tell if it might exist thought a particular path in the object graph that I'm not aware of. The reason it's hard to track all paths is that global objects point to many things.</pre>
