The clipboard manager only ever needs data if the original client is going to
quit or crash.

If we do not tolerate data loss when the client crashes, then I suppose we
always have to do wp_clipboard_manager.store() and it serves no useful purpose.

I think it's reasonable to tolerate clipboard data loss if the application
crashes (i.e. if the application is broken). Then GTK+ need only use
wp_clipboard_manager.store() when it's quitting (and would hang around long
enough to finish that operation after hiding its window). That way we don't
wind up doing extra IPC except when really needed.
