Hi,
Thank you, this is a very interesting read. I will share this with
friends as soon as this is publicly available in the TUHS archives.
We see premices of the Linux Copy-On-Write forking method!
I also note that they decided to avoid a global kernel lock.

This is perhaps the first significant document I wrote
at Amdahl.
Although undated, I believe this was written in August 1979, after I
had attended a 2 week class at IBM Chicago about VM//370(CP) internals
and performance.
The paper makes reference to V7 UNIX being "on order", so this is when
the V6 UNIX system was in use. IIRC, V7 UNIX was released in Nov. of
1979.

Huge thanks to my friend Karl D. for hanging on to this for 44 years.
