Unless I've completely misunderstood the entire memory managemeny scheme 
used by Gtk, once you call Gtk::manage(), you release all control of 
memory management to the library.  In other words, explicitly calling a 
widget's destructor ( or implicitly via smart pointer reference counting 
) would be 'bad'.  I say 'bad' cause I'm not really sure what you'd run 
into.  I imagine you'd start getting things like memory corruption 
errors or those fun messages about freeing the same memory segment 
multiple times.  Anyway, thats just how I had understood things.
