Suppose we have a job that is scheduled to execute every 10 minutes. Let's say that an execution of the job takes 22 minutes to complete. This will result in subsequent executions of the job being skipped. I actually have a TODO in SchedulerImpl.java to address this. I just needed to write up a ticket to document it. It needs to be addressed because a job that runs beyond its next scheduled execution will effectively prevent the job from any further executions.
