Adding a feature to the core OSG to address the needs of a single end user
that may or may not need this feature is not something I feel is
appropriate.

If there were no other way to solve the particular problem you are trying
to resolve it might be a compelling but there are number of different ways
to resolve the issue at your end:

   The exit from the application is entirely within end user control so you
can decide when it happens and what happens when you want to exit.

   The osgGA::Event/GUIEventAdapter system is extensible so end users can
subclass and dispatch their own events and have the event callbacks catch
these.

   After exiting the main frame/event loop you can call what ever you want
to call to do clean up.

These aren't the only ways either.

Robert.
