Right now shutdown is looping over *all* devicemapper devices and actively deactivating them, this is pretty slow if you have a lot of non-active containers. We instead only deactivate the devices that are mounted. We also do the shutdown unmount using MNT_DETACH which forces the unmount in the global namespace, even if it is busy because of some container having it mounted. This means the device will be freed when that container exits. Also, we move the call to waitClose to deactivateDevice because all callers of any of them call both anyway.
