Clem, Thanks for the reference to the Dijkstra paper. I had my electrical engineering education at the THE 1968-1974 and our introduction to programming class was taught by Dijkstra himself. Of course our exercises had to be programmed in Algol68 and run on the EL-X8 system described in the paper (entering programs on paper tape with a flexowriter). Interesting to read how ‘small’ the machine was in terms of memory and mass storage. The actual machine consisted of several cabinets.
Apologies for the off-topic post.

It where the idea of semaphores are defined and the idea of "up" and "down" - (aka P/V).
