The whole reason VM was developed at UCB was

V32’s static address space was not going to work.
Btw the program we used to debug the VM system on the original mc500 was
macsyma’s competition, sms (which would later become wolfram).
You probably meant "SMP",
yes thank you... typo/dyslexia (I did not notice the error until you
pointed it out).
In both cases
the idea was to ensure the memory system was being
exercised.
Nowadays we'd just run gcc :)

- as for wolfram vs SMP sorry not trying to dig into old wounds, just
trying to point out how ironic that two early UNIX VM systems used the same
style of application (symbolic math) as a way to find corner cases in the
VM code.
