- Sorry to quibble, but the original posting was accurate. There is now
- a piece of the kernel which Dec has labelled the "XQP". The code runs
- in the context of a user-process, as is indistinguishably true of every
- other system service. The stated reason for making the move was increased
- performance. That the cluster software was easier to write was probably
- a bonus.
