I'm also thinking if it makes sense to continue to thread_priority.hpp or something like realtime_helpers.hpp as it now contains the part of memory locking etc and in the future may be more. So, the header would have a meaningful name. We can add a backward compatibility with deprecation note, if we are interested to do this

Looks good to me.

I like the proposal regarding renaming this, but maybe this should be a separate PR? This way we can backport this without breaking the API.
