Unlike Task.sleep(for:), which goes through the global Swift concurrency clock, this routes the wait through libevent’s timer wheel — useful when you want sleeps to share scheduling with the same multiplexer that’s driving your I/O. Internally registers a one-shot timer via schedule(after:_:) and drives the loop until it fires.
