Or have to/from string converters, and have the rule that to go outside 
the process you have to do this conversion. I'm not sure where this 
comes up in the dbus codebase - it may well, in the config file or in 
the auth protocol. GlobalAddAtom() seems like it'd be a little scary... 
especially if it leaked out of dbus internals and effectively became 
some sort of public API...
