Sandy,

I think it was something that was missed in the port to YARN and the dead
code was cleaned up as part of HADOOP-8288.

If you have a use case for it or are worried about backwards compatibility
we can add it back in.  It is not that hard, all it did was add 'ulimt -v
<number>' to the shell script that launched the task, except on windows.
