How would you come to the conclusion that something is being "leaked"?

You'll probably going to have to:

1) Use precise language to describe your problem.

2) Produce a simple(r) test case which demonstrates it.

...if you truly want this fixed.  Perhaps I'm wrong, but I don't think
that anyone is going to want to debug a large application to figure out
what or if the problem is.
