* Ensure that referential integrity is not broken while

* reachable after the remote call has completed; even if
* it is being marshalled as part of an argument, the VM
* may determine that the reference on the stack is no
* longer reachable after marshalling (see 6181943)--
* therefore, tell the stream to save a reference until a
* timeout expires or, for results, a DGCAck message has
* been received from the caller, or for arguments, the
* remote call has completed. For a "local" LiveRef, save
* a reference to the impl directly, because the impl is
* not reachable from the LiveRef (see 4114579);
* otherwise, save a reference to the LiveRef, for the
* client-side DGC to watch over. (Also see 4017232.)
