I have been playing around with this and I think I know the root cause of
the hang in wait-for-atleast-N-buckets!. First I updated the python spout code
to not sleep. This was causing a race with the simulated time preventing the
metrics from being collected. The second issue is that
wait-for-atleast-N-buckets! does not advance simulated time. When I updated it
to advance by one second instead of Thread/sleep, it worked.
I attached a patch to the original JIRA.

I ran the tests 10 times in a row with no errors.
