Allen Wittenauer resolved MAPREDUCE-187.
----------------------------------------

    Resolution: Won't Fix

I'm going to close this as Won't Fix given the usage of cgroups and more.

> Currently mapred.child.ulimit cannot be used for anything other than for setting virtual
limits. It is hardcoded to set virtual mem limits (ulimit -v) only. This should be changed
so that other limits like open file descriptors, max user processes etc can be set.
