Isn't clock-pro supposed to leave the page right where it found
it, when it just scans a page and is not evicting it ?

That is, if the page came off one list, it should go onto the
other, regardless of accessed, hot/cold, etc. status...

This has the effect of the clock hand moving beyond the page.

Or am I overlooking something?
