> improve py_stress termination condition

> Key: CASSANDRA-905
> URL: https://issues.apache.org/jira/browse/CASSANDRA-905
> Project: Cassandra
> Issue Type: Improvement
> Components: Contrib

>
> Currently the stress.py script will sleep every (progress_interval) seconds
> and then check for termination. This can be confusing when trying to
> accurately use timing statistics based on the execution duration of the
> script. For example, if progress interval is 10 seconds then the script is
> guaranteed to terminate after N seconds, where N is some multiple of 10.
> I've attached a patch where the script sleeps every 0.1 seconds, and does a
> poll to see if the correct interval has passed in order to print information.
> The patch also ensures that statistics will be reported at the completion of
> the worker threads.
