;;; Patch file for System version 123.126
;;; Reason:
;;;  If the network is deconfigured before a full-gc, clear special variables that
;;;  refer to network data structures so that they can be reclaimed.
;;; Written 30-Nov-87 09:06:43 by pld at site Gigamos Cambridge
;;; while running on Jack Flanders from band 2
;;; with Experimental System 123.124, Experimental Local-File 73.3, Experimental FILE-Server 22.1, Experimental Unix-Interface 11.0, Experimental Tape 18.0, Experimental KERMIT 34.0, Experimental ZMail 71.0, Experimental Lambda-Diag 15.0, microcode 1754, SDU Boot Tape 3.12, SDU ROM 8.
