Hi Daisuke,
Most of my comments below are to do with style issues with cgroups,
rather than the details of the memory management code.

Another stray idea, for the master of stray ideas ;), how about (1) renaming
all the cgroup files as you like, Paul M, even including tasks to cgroup.task

Hi,
I was wonder if creating such library makes any sense at all,
considering the nature of cgroups, the way they work and their possible
application?
It seems to me that any attempt to create a 'simple' API would actualy
