Reviewed by Kimmo Kinnunen.
Currently, we clear the backend in response to a GPUP clear, which calls
prepareForBackingStoreChange.
That can trigger ensureBackendCreated if we didn't yet have a backend, which
will wait for the original backend (from the crashed process),
but does so by forcing creation of the new GPUP. This message never arrives.
clearBackend doesn't need to call prepareForBackingStoreChange if we didn't
have a backend yet.
