Access to kmem - System namelist - 'ps' etc

A long time ago on V7 I changed 'ps' to only read the name list once on boot,
then store the useful stuff in a file somewhere. It only then needs to check
that the file exists and do a stat on /(vm)unix to tell whether it really
needs to plow through the namelist once more. I'm sure a lot of others did the
same; I notice the most recent version of the 4.2BSD 'ps' from Berkeley does
it.
