ah... I didn't pay attention to the sample code :)).
Well, the problem is that poll() - according to the asio reference - just
processes *ready* handlers, w/o blocking(), so timer isn't waited. So, as
for your sample code, it shouldn't work even once, because noone waits for
the timer - but problably in your actual code there're some other parts that
run io_service and that's why it works sometimes.
However, if you call run() instead of poll() then the execution will be
blocked until the timer fires, and your sample code will work as you expect.
