title: What happens when a scheduled WebJob runs for a long time
body: <p>What happens if an Azure WebJob is scheduled to run but the previous running instance hasn't finished yet? Will it run the WebJob again so that two are running at once? Will it not run the WebJob and start the clock over? I haven't been able to find this behavior documented anywhere. I have a job I want to run hourly but it's possible that sometimes it might take longer than an hour to complete, but I never want two of them running at once.</p>
