    Description

      The JobTracker has a deadlock in the ExpireLaunchingTasks stuff.

      In particular, it locks the JobTracker and launchingTasks inconsistently.

      This deadlocks has been observed in the wild and causes the JobTracker to stop responding to rpc and http (other than the root page).
