Wondering was issue #963 Memory Leak ever resolved because I am experiencing a similar problem.
I am attaching a new trace delegate to multiple engines as part of a batch execution system. Each execution of an engine leaks more memory. I have taken a memory profile before and after and it would seem that the memory leak is a result of PythonTracebackListener,
as per attached screen grab.
