Oops, fixed.

> Assuming you mean loop.add_signal_handler() method, I would say that a minute-long delay is a sign of long blocking calls in your program.

During the delay for the callback to occur, I see my program logging work performed on other asyncio tasks and receiving timer events from another thread. So, not long blocking?
