Part of this seems to be due to the way CFS works.

CFS policy seems to make sense for a lot of workloads, but
there are some cases with kworkers where the CFS policies
just don't work quite right. Unfortunately the scheduler
problem space is not all that well explored, and it isn't
clear what the desired behavior of a scheduler should be
in every case.
