The names of all the different tools were hard linked together to the same giant universal desktop mega-app clusterfuck, which would run a different main loop depending the name it was invoked with. 

That must have been really early on because by the time I got to Sun (4.0?
Maybe 4.1?) shared libraries worked properly.
