Description

Currently the TaskMemoryMonitorThread kills tasks as soon as it detects they are consuming more memory than the max value specified. There are valid cases (see ~~HADOOP-5059~~) where if a program is executed from the task, it might momentarily occupy twice the amount of memory for a short time. Ideally the monitoring thread should handle this case.
