The future plans are still to be decided. The control on memory provided
by future versions of CPUSET might be to:
-associate one node on wich to allocate memory to each cpuset
-associate one allocation policy (local node first, round robin) to each

At first glance, limiting the amount of memory used will probably not be
in our objectives. The initial goal of CPUSET was obtaining good
performance on NUMA architectures. But this is an open question.

That's right.
