My main reason, apart from Bruce's points, is that it's not an expected component of libc and we've therefore made anything that uses strhash very non-portable. We should pull strhash out into a separate library which we can take with us to other platforms if we ever need to. There are probably other components of libc that we could do the same for. -- Paul Richards, FreeBSD core team member.
