Why on earth can't I use derez if I'm not invoking it from a window on
the console?  If I rlogin onto an A/UX system from my workstation, and
try to run derez, I get the following error message:

	Can't open user interface device
	/dev/uinter0: Permission denied

First of all, what is /dev/uinter0?  It's not documented in section 7 of
the System Administrator's Reference manual.  At the moment, it's owned
by the person who is currently logged in on the console; protection mode
is 0600.

Secondly, why does derez even care about /dev/uinter0?  Is there a good
reason (and, if so, what?), or is it just a bug?

Finally, what other A/UX commands have this (mis)feature?
