-- TerminateJobFlows shuts a list of job flows down. When a job flow is
-- shut down, any step not yet completed is canceled and the EC2 instances
-- on which the job flow is running are stopped. Any log files not already
-- saved are uploaded to Amazon S3 if a LogUri was specified when the job
-- flow was created.
--
-- The maximum number of JobFlows allowed is 10. The call to
-- TerminateJobFlows is asynchronous. Depending on the configuration of the
-- job flow, it may take up to 5-20 minutes for the job flow to completely
-- terminate and release allocated resources, such as Amazon EC2 instances.
