Where does the swap space reside?

Let m[0] ..m[4] be mutexes (binary semaphores) and P[0] ...P[4] be processes. Suppose each process P[i] executes the following:

wait (m[i]); wait (m(m[(i+1) mod 4]))0;
.......
release (m[i]); release (m[(i+1) mod 4]);

This could cause

When the result of a computation depends on the speed of the processes involved there is said to be

A counting semaphore was initialized to 10. Then 6 P (wait) operations and 4 V (signal) operations were completed on this semaphore. The resulting value of the semaphore
