Question:
Suppose that every monitor has a separate mutual exclusion lock, so that different threads can run in different monitors concurrently, and that we want to release exclusion on both inner and outer monitors when a thread waits in a nested call. When the thread awakens it will need to reacquire the outer locks. How can we ensure its ability to do so?
