Comment (by igaztanaga):

 BOOST_INTERPROCESS_POSIX_PROCESS_SHARED is not fixing anything as Mac Os
 does not support POSIX process-shared synchronization primitives.

 Starting in [85401] revision, all synchronization primitives based on
 spinlocks (for systems like Windows or Mac Os that don't support native
 process-shared synchronization primitives placed in shared memory) use an
 improved wait strategy, starting with a raw loop+yields for a OS tick
 (typically 10ms) and going to sleep after that. It has improved the
 performance and in most cases and CPU usage is very low.
