Signal handlers should be processed in main thread at the end, that's how

`asyncio.sleep()` always pauses the current task and switches execution to

`asyncio.sleep(0)` has no special meaning (but it has internal optimization for
the case).
Basically the same as `time.sleep(0)` for multithreaded program.
