Thanks Stefan, FWIW I don't see the merges on feature/noverlay yet.
Have you pushed?

Attached is what it looks like to remove itree_node entirely.  I like
the result, as I personally find sentinel nodes confusing and slightly
error prone.  I like my new implementation `interval_tree_remove` better
too.  Lemme know what you think.

It needs the 0003 patch also attached below or check_tree will crash.
