> 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.
