<ul><li>Asynchronous preemption is a feature in Go that allows the runtime to pause running goroutines at safe points.</li><li>It solves the problem of goroutines getting stuck in tight loops and blocking other goroutines from running.</li><li>When a goroutine has been running for too long, a signal is sent to initiate preemption.</li><li>The runtime manipulates the stack frame to inject a function call instruction, forcing the goroutine to reach a safe point and enable preemption.</li></ul>
