How do you think to implement "regular intervals", when you need a timer 
*message* for that purpose?

Perhaps we should distinguish between *blocking and non-blocking* 
polling. You seem to mention non-blocking polling, which can be used 
with multiple independent sources. The blocking version, as used to poll 
the event queue, puts the thread asleep until the event (new message) 
occurs.
