Doing it in dispose means the backend is actively tearing down itself, meaning various components might or might not be there, depending on how the tearing down is implemented. Make things a bit more robust by doing any work that might rely on the backend being there before shutdown is done in response to the 'prepare-shutdown' signal being emitted by the backend.
