+ ### This function is very similar to a lot of code inside
+ read_children_info, but that performs some tricks to re-use data between
+ different siblings.
+
+ ### We read the same few NODES records a few times via different helper
+ functions, so this could be optimized bit, but everything is within
+ a sqlite transaction and all queries are backed by an index, so generally
+ everything (including the used indexes) should be in the sqlite page cache
+ after the first query.
