An event loop runs in a thread and executes all callbacks and tasks in the same

To schedule a callback from a different thread, the

schedule a coroutine from a different::
loop.call_soon_threadsafe(asyncio.async, coro_func())
To handle signals and to execute subprocesses, the event loop must be run in
the main thread.
