* We are really looking for persistent memory leaks here not fluctuations in
memory use. There are too many false positives from memory usage increasing up
high part-way through the iterations and then reducing down for the final
iteration, which could be many lazy or deferred things running and completing
over time.
* Built entirely independently of the main renderdoc build (for now).
* Contains python scripts & framework for running tests on a renderdoc build,
which will be run nightly.
