 ### Why a Custom Wait Function?
 In real-time simulations, precise timing is crucial, as even small inaccuracies can lead to undesired behavior, especially when multiple threads interact and delays accumulate. The standard `usleep()` function may introduce unexpected delays because of how the operating system handles process scheduling, resulting in less precise timing.
