Subject stack trace from hung task
Date Fri, 05 Dec 2008 19:44:21 GMT

When a task tracker kills a non-responsive task, it prints out a
message "Task XXXXX not reported status for 600 seconds. Killing!".
The stack trace it then dumps out is that of the task tracker itself.
Is there a way to get the hung task to dump out its stack trace before
exiting?  Would be nice if there was an easy way to send a kill -3 to
the hung process and then kill it.
