so, i was using IRIX 6.5.2 with my $HOME mounted from an SS20 running
1.3.3.  certain programs (priv is one) run on the irix box cause my
ss20 to panic in the guts of the NFS server.  specifically, it hits
this panic message (which is in both nfs_syscalls.c and nfs_nqlease.c
though i believe i'm hitting the former):

	if (siz <= 0 || siz > NFS_MAXPACKET) {
		printf("mbuf siz=%d\n",siz);
		panic("Bad nfs svc reply");
	}



why doesn't we just free the mbuf and continue here, rather than
panicing?
