For variables not defined as volatile, (e.g.) pthread_mutex (and similar

A mutex may be able to atomically block access because of its own
memory barrier, but I would suggest that employing such a technique on
multi-core systems will not ensure an accurate value.
pthread_mutex() does guarantee that. I don't know about the Windows
equivalents.
