implemented in CP67 kernal ("subpools") code 1970 (released CP67
R3) ... following from presentation I gave at SEAS 7Oct1986 (European
SHARE on isle of jersey) loots of R3.0, R3.1, & R3.2 was after I had
graduated and joined scientific center and stuff I had done at the univ
as undergraduate in the 60s (one of my hobbies was enhanced production
systems for internal datacenters).

repeated 16Mar2011 at Wash DC HILLGANG user group meeting. 

In the morph from CP67->VM370, they dropped and/or simplified a lot of
stuff. 1974, I started migrating a bunch of stuff to VM370R2 base for my
internal CSC/VM ... including kernel reorganization for SMP
multiprocessor (but not the SMP support itself). Then for VM370R3-base
CSC/VM I do SMP support ... originally for the internal online
sales&marketing HONE systems (before it was released to customers in
VM370R4).
