If you're going to blue-sky this, move RMS and the XQP into a user-mode 
process, preferably with zero-copy buffering.

Whether a solitary process or replicated processes would depend on 
complexity, aggregate system load, and available cores.

Yeah, I know, I'm making a mach-ery of the existing two-by-two version 
of the four-mode design.

But pragmatically, VSI has a few billion projects in the queue ahead of 
re-architecting the RMS and XQP giblets.
