question about winbindd.c in samba 3.0.25

[Herb Lewis]

The end of the main function in winbindd.c has the
following code

         /* Loop waiting for requests */

         while (1)
                 process_loop();

         trustdom_cache_shutdown();

         return 0;
}

Previously (in 3.0.8 - not sure where it changed) the while (1)
was inside the process_loop function and there was a way to break
out and then return and execute the trustdom_cache_shutdown function.

Now it appears that trustdom_cache_shutdown can never be called.
