Well, I discussed that before with Arjan and he said he would maintain
CPUidle if Len didn't have the time, but it seems he didn't expect that
there would be a lot of work on it in the near future.

So, I suggest that if neither Len nor Arjan reappear shortly, people can
send CPUidle patches to me.
