Ah, that seems pretty simple -- I like that a lot!

With this approach, we can use the current returnArgument: method.  
I.e. just make that method not close the window (when window has been  
opened as async).

Two things I am wondering about:

   1) should tm_dialog -a really return a plist? because we _always_  
want just the token?
   2) should --wait-for-input only return the arguments given to  
returnArgument:… or the full data model? Here I wouldn’t say we  
_always_ want the former, but 99% of the time, we would.
