On a similar note, me and Joel were discussing about prctl and it came up
that, there is no mechanism to set cookie from outside a process using
prctl(2). So, another option we could consider is to use sched_setattr(2)
and expand sched_attr to accomodate a u64 cookie. User could pass in a
cookie to explicitly set it and also use the same cookie for grouping.

Haven't prototyped it yet. Will need to dig deeper and see how it would
really look like.
