 * Dummy session backend
 *
 * This isn't a real backend, but implements some methods that SessionBackend
 * does so tests can run.
 *
 * FIXME This class is a huge hack, and it won't work e.g. as methods in Session(Backend) are typehinted.
 * SessionBackend should be mocked directly instead, but that's currently impossible because the class is final.
 * At the very least, there should be an interface that SessionBackend implements, and that could also be used
 * for mocks.
