Alan, I'll start looking for a copy of the article on VM/370. Multiple virtual processors on a second level machine was a significant step forward with ESA. ESA's address space and access register useage is interesting but I don't want too explore things in the article that might not appeal to a broad audience of programmers interested in operating systems concepts.
Thanks for the reference and if you think of any on second level parallel processing let me know. I'm going to look for material on the Java VM and unicode related material.

I think you are referring to L.H. Seawright and R.A. MacKennon's article "VM/370 - A study of multiplicity and usefulness" in the IBM Systems Journal, vol 18 no 1, 1979. The whole journal is devoted to VM/370. Alan Altmark Sr. Software Engineer IBM z/VM Development
