	I wish I knew more to help...  Anyway, I 
patched/recompiled/installed/tested.

	Note that I can't run the 1.3.70 klog - I get a "Illegal 
instruction(coredump)", so I tested w/IBM's 3.6-p9 klog.  The system 
didn't crash immediately after getting the token, only after I cd'ed to 
my AFS home directory.  (Earlier, I cd'ed without a problem, but a few 
seconds after the klog it crashed.)
