Explore how to use semaphores to throttle threads and control concurrency by limiting the number of threads executing a memory-intensive code region simultaneously, preventing system thrashing and improving performance.

One other simple use case for semaphores arises on occasion, and thus we present it here. The specific problem is this: how can a programmer prevent “too many” threads from doing something at once and bogging the system down? Answer: decide upon a threshold for “too many”, and then use a semaphore to limit the number of threads concurrently executing the piece of code in question. We ...
