Yep, these are hard. Which method is your favorite?
My original purpose was to fix a bug as I described.
This bug and the problem that offering big enough array for a huge
cgroup are orthogonal!
Could you consider/test that is it a bug as I described(and is it as
critical as I described, maybe I was too nervous)?
And this is also a problem: opening a cgroup.tasks twice or will waste
a lot of _physical_ memory.
Thanks! Lai
