Because ps is a much more complex program and used much more 
extensively. Aside from having quite a few options to process, the work 
that it does would be much more expensive to do in rc, although a fairly 
speedy implementation could probably be written without much trouble.

But your lsof is equivalent to about 3 lines of rc script, done almost 
entirely by programs written in C, and is much clearer. I doubt that 
there's any noteworthy difference in speed, or that it would matter much 
if there were, so I just can't imagine why you'd want to write it in C.

The worse your line is tangled, the better is the
fishing around you.
