> The ExpireLaunchingTask thread kills the task that are scheduled but not responded.
> Currently if a task is scheduled on tasktracker and for some reason tasktracker cannot put it to RUNNING.
> The task will just hang in the UNASSIGNED status and JobTracker will keep waiting for it.
> JobTracker.ExpireLaunchingTask should be able to kill this task.
