Yes, because of all the libraries to be parsed, it's slow to load  
everything, and we should be able to avoid this overhead as much as  
possible. What ideally should happen is that external Gtk widgets/ 
resources could adopt or inherit the pattern of ExternalResource (also  
used by File, Socket, Directory, and ExternalLibrary objects), in that  
there is a "locator" attribute which stores some description of how to  
recreate the resource, and then startup/shutdown methods construct and  
teardown the actual objects in question. The ExternalResource also  
keeps a "handle" attribute for the low-level identifier that the VM  
gets and then passes into the image. ExternalResources also has a  
parentResource attribute which is currently used for the  
ExternalFunction-ExternalLibrary relationship but basically helps  
determine the part-subpart dependency structure, in that the children  
depend on the parent resource being enabled before they can be  
(re)created and work.

In the window's case, the "locator" might be an array specifying  
dimensions, and maybe a display tree of widget children along with  
their dimensions and attributes. I'm hand-waving at this point, but  
does this make sense as a way to think about the problem?
