Eli Collins commented on MAPREDUCE-1085:
----------------------------------------
What branch do you see this code in? I don't see the code you're referring to
on trunk or 21. There's only one caller of getVMSetupCmd and it's fine with
the null return value.
> For tasks, "ulimit -v -1" is being run when user doesn't specify
> mapred.child.ulimit
