probably in contrast to "pre-emptive multitasking"
Apple's OS didn't have it until OS X (I'm told, I thought they'd gotten it
There has been little if any literature on the topic of 'antagonistic'
multi-tasking vs. whatever you want to call it (we called it cooperative),
so I guess "ours" just never came into common usage.
if I had to hazard a guess, I'd say that someone thought it was too
difficult to write a pre-emptive system and chose to call it "cooperative"
as a marketing ploy. Given that pre-emptive systems were in use to my
personal knowledge in 1967, it seems odd that someone would do that,
words get usurped, or their meaning will 'drift' as time passes, so it's
really hard to say.
