It will - the visited is clear only for blocks I need to visit.  In case I am
computing internal loop, it is clear only for nodes in internal loop.  In the
final run, it is clear for all blocks.

I see why it is confusing.  Perhaps the visited should be named better to
represent this functionality.  Maybe reverse the meaning and call it tovisit?
