Hi Boris,

Following your example, I have written my own extension. I found that when
I register signal handler for shutdown my application
manually, the application required ctrl-C twice to be shutdown. Then I go
back to check the example, adding the same signal
handler - it acted the same way. Should I book all io_service(s) for stop
them externally?

Here is a the example modified that uses sleep() rather than Windows API.

Best wishes,
