Andy Ross c782d07a1c tests/kernel/smp: Properly synchronize CPU counters at test start ... The idea behind this test is to race two CPUs against each other, validating that each is truly running simultaneously. But it just assumed that the other thread/cpu would start synchronously as soon as k_thread_create() returned. Normally, that works fine. But while debugging I added some code that was slowing down entry to the other thread (or maybe the return from k_thread_create() into the main thread) long enough to allow one thread to get a significant head start. That breaks the logic in the test and things were inexplicably "failing". Put a spin loop around the count so that the main thread can start counting to within the memory system's ability to inform it of the change from the other thread.
