[Pharo-users] logging/tallying what is getting garbage collected?

Is there a way to learn what is getting garbage collected in an image? In a part of an application I've written the Qwaq profiler & Pharo profiler consistently report that 2 full GC's (3% uptime) and ~400 incremental GC's (9% uptime) are run. That makes me think I'm creating and discarding a bunch of stuff and maybe I don't need to, but I also don't have a strong idea where to begin looking. Thanks Paul
