You are not getting asynchronous timeouts, all you are seeing is the 
first timer being cancelled when you queue the second.

All asio async actions happen in the context of the io_service, you need 
to call io_service.run() somewhere.

You have either oversimplified your example or you need to re-read the 
asio examples.
