> {{SortedIndexLocker#acquireLockNextKey}} is poorly implemented and not tested properly. It ignores the documented contract of {{hasNext}} and {{peek}} from {{{}PeekCursor{}}}.
> "Has next" checks must essentially be replaced with {{{}peek() != null{}}}.
> Unit tests, that would simulate concurrent operations, or maybe even do concurrent operations, must be implemented.
