As with the Python updates, we don't want to permit this code to swallow the exception, gdb_exception_forced_quit, which is associated with GDB receiving a SIGTERM. I've adopted the same solution that I used for Python; whereever a gdb_exception is caught in try/catch code in the Guile extension language support, a catch for gdb_exception_forced_quit has been added; this catch block will simply call quit_force(), which will cause the necessary cleanups to occur followed by GDB exiting.
