Well, I just stuck this in the middle of my .profile this morning...
seems to work:

test -n "$program" &&
	sec=8 &&
	trap 'trap 2' 2 &&
	echo "you got $sec seconds to interrupt before
		\"$program\"... \c" &&
	sleep $sec &&
	trap 2 &&
	eval $program

Bernd> Hope that does the trick.
I hope so too... even though there might be tiny intervals where an
interrupt would spoil the fun.
