Path Compression / skipped bits
Any given tnode is linked to from the child array of its parent, using
- a segment of the key specified by the parent's "pos" and "bits"
+ a segment of the key specified by the parent's "pos" and "bits"
In certain cases, this tnode's own "pos" will not be immediately
adjacent to the parent (pos+bits), but there will be some bits
in the key skipped over because they represent a single path with no
