I've had a bug report that Clang's ThreadSanitizer presents a warning in this function. Having reviewed this, this does
actually make sense. However, since CPU caps should never differ for a running process, I don't think the trade off of
complicating internal API's by passing around CPU caps versus just disabling the warnings is worthwhile. I'm therefore
just going to disable these warnings.
