@jhuber6 I fixed the containers, removed most locks and made some cleanup. I also added a new routine that handles deinit with Errors. 

About the locking, all the current cases require the fine-grain locking so I'm not sure if it's worth it to add the option I mentioned at this point (but we could do that later).
