	(AIX 5.1, openafs 1.3.70 + above + rx.c changes from 8/18)

	Well, that's closer.  login and klog work, as does (nominally, at 
least) AFS file access.

	But, after I go to AFS space and play around (and I think it has to be 
non-cached access), and return to NFS space, the process (and I think 
any NFS process from that point on) hangs up.  The system is still 
running, topas is showing nothing exciting, and as long as existing jobs 
avoid NFS, I'm OK.  Touch NFS, and it hangs.  Here's a (to me 
meaningless) kdb "proc" output for a hung "ls" command.
