Basically, the atomic Variation has got to have a lock to be able to guarantee thread safety, and also is bumping the ref depend on the article (plus the autorelease rely to balance it) so that the article is certain to exist for your caller, or else there is a possible race issue if An additional thread is location the worth, creating the ref depend to drop to 0.

The thought Atomic Wallet was that two procedures shouldn't be ready to modify precisely the same data simultaneously.
Inside a grandfather clock, a 2nd may be defined as enough time with the pendulum to go back and forth after; in the quartz oscillator of a wristwatch, it is typically about 32,0000 vibrations on the crystal.
It's like using a retina Show and A different Show at fifty times the resolution. Why waste the methods to get that amount of performance if it can make no change to any person? Specially when strong code can conserve days of debugging...
Sure. Multithreading indicates: numerous threads can study a shared bit of facts simultaneously and we is not going to crash, however it doesn't warranty that you are not studying from the non-autoreleased price. With thread basic safety, It truly is guaranteed that Anything you examine just isn't car-introduced.
