This is about kernel programming - people should care. We have enough crap
as it is. timer wheel is fast as well, but everything has its limits,
putting this focus completely to delivery is nonsense. It can't be that
difficult to put together a decent list of criteria, where to use which
timer. Both are still _timer_, introducing this timer/timeout thing is
only confusing.
