So this is not supposed to work:
Precisely, it is not /guaranteed/ to work if that's what you meant.
(Please also note that "give up time slice" does not mean very much on a
multi-core/CPU system when the threads are running on different cores/CPUs
and thus in "real" parallelity. But I suppose you know that.)
As assigning a value to myList in one thread is only a very short time
before the other thread reads it, it's very likely that the wrong value
is still be in the cache of the worker thread's processor and make it
crash.
But is is just a very extreme example of a behavior that mostly is
assumed to work and according to your wording would be bound to fail.
Ass-U-Me. You know. ;) - Yes, this is bound to fail.
