Chris Westin commented on DRILL-1942:
-------------------------------------

The script output and the above message says it created the review, but it didn't, and the
file it attached here is empty. I'll hand upload a real patch file here, but I can't get review
board to accept the file for the moment....

> We're using a lot more memory than we think we should. We may be leaking it, or not releasing
it as soon as we could. 
> This is a call to come up with some improved tracking so that we can get statistics out
about exactly where we're using it, and whether or not we can release it earlier.
