      Description

      TaskMemoryManager currently works only on Linux and terminates tasks that transgress memory-limits by first calling TaskTracker.purgeTask() and then explicitly destroying the process tree to be sure that the whole process tree is cleaned up. After HADOOP-2721, we don't need this explicit process-tree destroying as the usual code-path of killing tasks itself takes care of cleaning up the whole process-trees.
