The new boost::mutex implementation uses a semaphore to handle contention,
which you can do a timed wait on. Interlocked operations are used in the
first instance, to detect contention, and avoid waiting on the semaphore
unnecessarily. This is essentially how a Critical Section works, but gives
us greater control.
