--- Comment #10 from Mark Johnston <markj at FreeBSD.org> ---
(In reply to Ed Maste from comment #6)
I tried replacing the section list with a red-black tree, ordered by section
index.  It reduced the runtime of "strip libHSCabal-" from 1m20s to
52s, so this isn't the only problem.

>From reading the elfcopy code, it looks like the strip implementation is just
naive.  We copy each elf file in the archive into a temp archive, during which
strip does its filtering, and finally rename the tempfile over the original. 
So even if strip has nothing to do, it ends up doing a lot of work.
