Overview
This simply sets up the scanning routines with the parameters for the desired hole. Note that there's no need to specify allocation flags, since they only change the place a node is allocated from within a suitable hole.
Warning
As long as the scan list is non-empty, no other operations than adding/removing nodes to/from the scan list are allowed.
