I wonder if we should think about a more structured kernel API for
modifying these kind of system registers so we always have the
up-to-date values stored in memory. Many of them do need to be
restored after sleep, but they don't need to be saved per-thread
or saved every time we go to sleep.

Yes that's on my mental TODO. Paul and I have talked about it in the
past for KVM.

I'll write it down sometime so we at least remember :D
