you (and many other people) are confusing what I've proposed (use cgroups
to indicate what processes to care about and what ones to not care about
when deciding to suspend/go to idle) with the prior cgroup proposal (use
cgroups to freeze a subset of tasks while leaving others runnable)
The decision on whether or not to go to sleep isn't the difficult bit of
this problem space.
