How is it more powerful? The next step in introducing such API is that
people start complaining, they don't get ms precision, which of course is
fixed by the next patch, with then results in that the whole timer system
becomes more complex for a few misguided users.
Keep the thing as simple as possible and jiffies _are_ simple. Please show
me the problem, that needs to be fixed.

bye, Roman
