Contention isn't the worst problem here - I'd expect the cacheline ping-pong
to hurt more... I agree with the analysis, but I'd really like to avoid that
spinlock ;-/

Let me see if we can avoid that... Oh, well - at least that's a good excuse
to take a break from fucking deadlock analysis around the damn acct(2), most
of VFS and network filesystems ;-/
