What's "pseudo time" when used in comparison with semaphores I'm currently listening to Alan Kays' talk "Is it really complex or did we just make it complicated ?" (https://www.youtube.com/watch?v=ubaX1Smg6pY&amp;= ) where he says that "semaphores were a bad idea and there was something called pseudo time that was superior" (at 51:40 on the linked video).
Maybe I misunderstood the word "pseudo time", but do you know anything about those ?
I believe he may be referring to this paper: NAMING AND SYNCHRONIZATION IN A DECENTRALIZED COMPUTER SYSTEM.
