Module source 

IoSource — RAII wrapper that registers an OS handle with the reactor.

Constructing an IoSource registers the handle; dropping it deregisters. The readable() and writable() methods return futures that resolve when the underlying OS handle becomes ready.

Waker integration: on each poll the future stores the current waker in the reactor’s WakerRegistry. When the reactor fires an event for this token the stored waker is called, re-scheduling the waiting task.
