Comment(by fryguybob):
I'm happy to write a patch for this. I think there might also be a
problem with {{{num_updates}}} and {{{current_value}}} being different
memory locations on architectures with the right kind of relaxed memory
ordering (ARM?). I'll look into that and make a separate issue if I find
anything.
