Damien George 13195a678d webassembly/asyncio: Schedule run loop when tasks are pushed to queue. In the webassembly port there is no asyncio run loop running at the top level. Instead the Python asyncio run loop is scheduled through setTimeout and run by the outer JavaScript event loop. Because tasks can become runable from an external (to Python) event (eg a JavaScript callback), the run loop must be scheduled whenever a task is pushed to the asyncio task queue, otherwise tasks may be waiting forever on the queue.
