Something something exception that proves the rule? I'm not familiar with QNX other than knowing that it is a an RTOS... which I imagine imposes some constrain

  It runs in millions of cars and other embedded systems, not that niche tbh. Your "exception" is the rule for a lot of engineers. But yes, they took pride that process switching is as efficient as thread switching which is a slick way of selling that they never optimized threads to be better, unlike Linux. Until QNX8 there is also the "big kernel lock"...

Hell, even JavaME does; or at least did, not sure what current status is. That's not really a worthwhile comparison. My 'niche' mention was in relation to number of devs who'd be familiar with it. > Your "exception" is the rule for a lot of engineers. Now, that's a fair comparison... but I wager "a lot" is still not nearly the number of engineers/devs that work with e.g. Linux. That's not to cast any aspersions, of course. After all it's often not really a choice of the engineer's part. Not sure how we got to this tangent, tbh.
