How do I clear records from Google App Engine's Mapreduce
===

I'm running MapReduce jobs off a cron on App Engine, and I've realized that I now have thousands of entires in my /mapreduce/status page.

Is there a way to get rid of them easily, other than manually clicking "Cleanup" on each of them?

How would I modify the code to automatically clear the job info if it completes successfully?  Do I have to modify the SDK to do that?
