We moved the instance of smo::Mind to global scope. I suppose we'll only support one instance of Mind per SMO process at least for now. We now track the state of Mind threads' JOLT-waiting. This allows us to centralize the Mind thread shutdown logic. Mind::finalizeReq() now takes care of all Mind thread shutdown state logic by tracking whether Mind threads need to be JOLTed first before being told to exit.
