[keycloak-dev] KeycloakSession question

Is KeycloakSession always short-lived? If so, it might be relatively easy to make the JSON File based persistence more robust and probably fix the cache tests that currently fail with it. All KeycloakSessions would share the same in-memory model. When a KeycloakSession ends and requests to write the model to disk, all new requests for access to the model are blocked. When all active KeycloakSessions are done, we write out the model and unblock the new KeycloakSessions. But this only works if we can assume KeycloakSession is short-lived.
