Ok.  Watch for any fallout on non-arm systems.  I'd always invite people who think they know the best way to test volatile to chime in.  There is the new infrastructure to test multi core synch issues with gdb trickery.  As you want more beef, you can consider it.

I'll note that I do sometimes wonder if this type of code isn't better handled in #if feature tests inside the testcases themselves.
