When detaching, we make sure no application IO is in-flight by internally suspending IO, then trigger the state change, wait for the result, and finally internally resume IO again. Once we triggered the stat change to "Failed", we expect it to change from Failed to Diskless. (To avoid races, we actually wait for it to leave "Failed"). On an unresponsive local IO backend, this may not happen, ever. Don't have a "hung" detach block IO "forever", but resume IO before waiting for the state change to Diskless. We may well be able to continue IO to and from a healthy peer.
