This would be very useful.
When I've needed this, I didn't want to see everything in the system.
In an effort to avoid performance problems and major changes.
Insert a soon to be designed trace object as a member of the instance you
want to trace. It captures file/line number ...
Haven't I seen this sort of thing here before ?

For those times when you have no idea where to begin.
sys.settrace could be used in some way to watch everything. Slowly yes.

The output could be analyzed for cyclic references. Run this like a lint.
Now that you've found the cycles could some code be auto generated to handle
the clean up ?
