It might be necessary by some emulated HW to perform the tick after one

tick by the ptimer user itself, let's make ptimer do the delayed tick.

Isn't this related to previous patch? It is kind of a rounding problem

Ah, you probably meant "Legalize running with delta = load = 0 and abort on period = 0" patch. Yes, they could be squashed.

I chose wrong policy at first time, further added MPtimer tests revealed it.
