Since bootstrapSearch was rewritten to use the node cache, it made it clear that
refill should be rewritten as such. However, then bootstrapSearch becomes
irrelevant.
An enhancement to refill is that it will let insertNode review its whole list
of nodes and then let it insert nodes up to SEARCH_NODES nodes. The previous
method would not garantee this behavior since, most of the times, it would pass
less than SEARCH_NODES nodes to insertNode.
