the misbehavior doesn't manifest itself too badly when overly long timeouts
don't have a bad effect, and when there is sufficient network traffic to
constantly wake up the main loop from its overly long sleep, as it is often
the case when using a tun/tap interface (probably the function's main user)
and the host system is chatty about mdns and what not.
