Excellent - appreciate your efforts, and no pressure on timing from our side. As for the SDK you ask about that eventually triggers `OSSpinLockLock` (via `libcompiler_rt`'s `__atomic_load`), @cjappl will have to report back as I'm not able to get it to work on my machine. @cjappl - could you confirm?
