Description

For debugging map/reduce jobs, if a single task is producing bad results, but not failing, it is hard to debug the problem. This patch lets you set a pattern for task ids that will keep their files from being deleted when the task and job complete. This allows the developer to run the task in the IsolationRunner under the debugger.
