> We should extend the existing stress test to have a new mode designed to test memory-based admission control, where the stress test framework does not try to throttle memory consumption but instead relies on Impala doing so. 
> The required changes would be:
> * A mode to disable throttling
> * Options for stricter pass conditions - queries should not fail with OOM even if the stress test tries to submit way too many queries. 
> * However AC queue timeouts may be ok.
> * Investigation into the logic for choosing which query to run next and when - does that need to change?
