I'm looking for real world examples of needing read and write access to the same value in concurrent systems.

In my opinion, many semaphores or locks are present because there's no known alternative (to the implementer,) but do you know of any patterns where mutexes seem to be a requirement?

In a way I'm asking for candidates for the standard set of HARD problems for concurrent software in the real world.
