It's been a long time since this discussion, I just wanted to add that I've been recently able to confirm the ability of memcg to prevent single users from DOSing a system by "make -j" - in a real-world scenario (using linux-3.2.1). So thanks to all who contributed to the solution in whatever way :-) (A minor issue remained: The kernel is very verbose when killing tasks due to memcg restrictions. In fork-bomb like scenarios, this can lead to high resource utilization for syslog et al.)
