I have since found I don't get the messages when I (setq
process-conection-type nil) in Xemacs (forcing it to use pipes instead 
of ptys).  So it is specific to fhandler_[pt]ty*.  Of course
interacting through pipes is not really desirable and leads to other
problems.

What is interesting is the message refers to /dev/tty1 which shouldn't 
be involved, it ought to be /dev/ttyp1 (if the virtual device names
are Unixy-sensible at all).
