An example of use of _reviveHook().

* description

Client passes an object of Data to Server. We want to make Data that
always holds the local hostname. For example, Data holds the local
hostname of the client before passing. After passing, Data holds the
local hostname of the server automatically. 

Data._reviveHook() takes care of such automation.

See examples/persistent/Data.java for another example of _reviveHook()
and _freezeHook().
