Semaphore is a nonnegative integer count. Semaphores are
typically used to coordinate access to resources, with the
semaphore count initialized to the number of free
resources. Threads then atomically increment the count when
resources are added and atomically decrement the count when
resources are removed.
When the semaphore count becomes zero, no more resources
are present. Threads that try to decrement the semaphore
when the count is zero block until the count becomes
greater than zero.
