I recall trying it last time.  In fact, I would use it anyway, because 
you are always building the archive from scratch, so 'q' should be safe.

However, it still didn't help much.  If I get some extra time, I can 
make a measurement, but I think I decided that the problem was due to 
the overhead of ar opening and closing the library each time, probably 
spending some time digesting whatever directory info is there.  I also 
seem to remember that I would print a line for each append, and it would 
slow down drastically as the library grew larger.  (It's been a while, 
so I won't swear to it.)
