+     * calls that have been interrupted by the occurance of signals.
+     * System call restart is achieved by restoring the saved state at the
+     * time of the system call trap, and re-issuing the system call.
+     * Arguments to the system call are saved on the kernel stack, and 
+     * the address of that array is passed as an argument to the dispatcher.
