Improvement: Make object operations threaded
Summary:
Currently all object operations seem to be single-threaded. Each object node tracks its next, previous and parent nodes, making it unable to parallelize. I wonder if we have a top-down tree reference to existing objects, and whether it's possible to port actions like adding, deleting, etc. to use such a reference, making it possible to parallelize.
Steps to reproduce:
