Golang Concurrency Patterns: Waiting and Signaling with sync.Cond

sync.Cond in Golang is a synchronization primitive that can block a goroutine until a certain condition is met. It consists of a Locker (usually a mutex) and a condition variable upon which goroutines can wait or signal. It's typically used in scenarios where goroutines must wait for other events before proceeding, enabling efficient resource utilization without busy waiting.

This example demonstrates a goroutine signaling another through a sync.Cond variable. It waits for a condition (a simple state change) before proceeding, showcasing an efficient way to synchronize state between goroutines.
