Back in 1981 autolocking and locking files existed, but you'd
have to be running basser's much hacked 32V. It had resources
limits too.
By 1985 it had copy-on-write fork an 'fast' [one] context switches.
And kre thought 4.2BSD was fast...
IIRC think basse[rt] were 45% faster.
Of course, this took years of work by several people.
