In 6940310 we introduced versions of the push() and pop() methods on the CMRegionStack class that use locks to deal with failures that were caused by the MT-unsafe use of the lock-free push() and pop() versions (push() can be called concurrently, pop() can be called concurrently, but push() cannot be called concurrently with pop()). However, for performance and scalability reasons, it'd be good to go back to use the lock-free versions.
