A non-obvious ramification of this change (but one which is probably  
good) would be that nodes with fewer peers get a better shot at having  
a valid position. Right now, whenever a node with a bunch of peers  
looks to swap with a node with only one or two; it will pretty much  
*always* get the position it wants (because each peer is weight the  
same & the general position is looked at).

This is the effect which Zothar previously brought to mind; that  
darknet-only nodes (fewer connections) tend to roam a lot more.
