No, he doesn't.  The function to look at is gdb-reset.
(gdb-delete-frame-or-window is just what causes GDB to quit, but when
it actually does, the comint process sentinel kicks in and calls
gdb-reset.)  But for gdb-reset to do what Sam wants, gdb-setup-windows
should record the configuration of windows before it sets up the GDB
windows, otherwise we will have no information about the previous
window configuration.
