Except (a) it can't ignore $TERM and/or $TERMCAP and still "work", and
(b) it doesn't ignore $TERMCAP, or changing $TERMCAP to a filename
instead of the termcap entry wouldn't've changed anything.  (And it
quite definitely doesn't ignore $TERM.)

I just checked, and top is sgid on the 1.4T machine but is not set-id
of either sort on the 1.5.3_ALPHA machine.  This makes it even more
baffling to me, as it runs directly counter to (the implications of)
what you said.  Now I _really_ don't understand what's going on.
