Gtk-- refcounting question

[Brian Alexander Martin <briam cats ucsc edu>]

I've got a question about the current status of refcounting in gtk--. 
  
I've noticed that not all the widgets support the ref()/unref() methods. 
Specifically, I'd like to be able to fiddle with the reference counts on  
Gtk_Adjustments.  It looks like all that would be necessary would be to 
make a call to gtk_adjustment_{ref,unref}.  Hmm, maybe I'll hack this out 
and see what happens :)
