Turns out we were cloning permissions which after prompting were discarded, so the state of permissions was never preserved. To handle that we need to store all permissions behind "Arc<Mutex<>>" (because there are situations where we need to send them to other thread). Testing and benching code still uses "Permissions" in most places - it's undesirable to share the same permission set between various test/bench files - otherwise granting or revoking permissions in one file would influence behavior of other test files.
