 As explained in the previous section, AmbientTalk's remote references are by default resilient to disconnections. This has significant repercussions at a distributed memory management level. The main impact is that an exported object cannot be reclaimed when all of its clients are disconnected since the remote references remain pointing to the server object. In other words, servers objects are kept alive even though there are only remotely accessible by a disconnected remote reference. AmbientTalk provides built-in support to unexport explicitly remotely accessible objects by means of the ''takeOffline'' language construct. The construct look as follows: As explained in the previous section, AmbientTalk's remote references are by default resilient to disconnections.
