Your .Xauthority is not world-readable, and xterm is dumb enough to try and
read it with its setuid-bit in effect. This will (usually) fail on a NFS
mounted filesystem. Unless all of the file bits are in the local machine's
cache, in which case there won't be a NFS read call to the server. Note that,
on NFS filesystems, it is the read call (not open(2)) that returns
"Permission denied" (esp. for processes running as root).
