Transient references
Transient remote references are managed by object spaces and have strong identity semantics. A transient remote reference is automatically generated by the system when a local object is passed out of its containing space (for example, as an argument or return value). As the name implies, transient references are only valid for the duration of that run of the exporting object space. During that time, however, object identity is strictly maintained and object spaces importing a transient remote reference ensure that all local uses of that reference use the exact same remote reference object. That is, passing the same local object to a remote space twice creates only one remote reference object in the remote space.
