Checking for reference leaks

[Dan Davis]

So, my application apparently is the largest on our Django servers.   This doesn't mean that a reference leak exists, but it could mean that a reference leak exists.  I've been trying to find some generalizable way to search for such a problem.  I have difficulties drawing help from within the organization, because I am one of the two most expert with Python/Django.

I've written a "leak checking WSGI middleware", hoping to force Django to serialize completely.   It hasn't worked, really.

Can someone review this gist and suggest any changes:
