Hi Jack
did you check PointerFinder?
I can search for reasons why a certain object isn't garbage collected. I'm a quick port of a VisualWorks program written by Hans-Martin Mosner. Call me as shown below. I'll search for a path from a global variable to the given object, presenting it in a small morphic UI.
Examples:
PointerFinder on: self currentHand
PointerFinder on: StandardSystemView someInstance
Now, let's see why this image contains more HandMorphs as expected...
HandMorph allInstancesDo: [:e | PointerFinder on: e]
would be nice to get it a better interface.....

I am new to Pharo and Smalltalk, so this should be a good learning experience. I am using the A* algorithm for starters, but would like to have a variety of pathfinding options using different algorithms.
