	RealQuick> kernel being based on FreeBSD and Mach 3.0 technologies
...
	Last I recall hearing anything, it sounded like:
		NetBSD for some ppc-specific stuff
		FreeBSD for some md kernel goop
		NetBSD and/or FreeBSD for userland stuff
...

The NetBSD and FreeBSD references are something along those lines, but
I can't remember where I read it either.

But I never quite understood the bit about the Mach stuff, as I have read
on the NetBSD site that;

	"UVM completely replaces the Mach based 4.4BSD VM system"

and that many other parts of the Mach-based kernel have been updated to
improve reliability and performance.
