Persist REST state #48

The overall approach seems fine, aside from the comments/questions I added.
In general do you feel the existing tests are sufficient to cover these changes? I might be missing something, but I don't see any that create more than one blockade in a single deployment, so that seems like a gap.

I think you need to declare these two as global if the changes are to stick. However, is there a reason to use global vars at all? Perhaps all three of these vars could be on the class instead?

I'm not too familiar with Flask - are there multiple request handler threads? If so this behavior seems racy. Concurrent requests could step on each other. delete_config too.
