Something I've found useful in the past was to use ObjectSpace to 
create a histogram of counts of extant objects by class. I take a 
snapshot, run for a while, take another, and so on. If one particular 
class of object shows an increasing number of objects, then I can focus 
in to see if I'm keeping references that I shouldn't.
