I remember discussions on this topic long ago. It was like GTK (GTK 1 at 
that time) isn't tolerant to exceptions that occur in its signal 
handlers (read: in LCL and user's code), and it wasn't possible to 
expect program stability after an exception was raised. That explains 
the need for 'terminate' button.

The things may have changed since then, however.
