Too bad we're not seeing -Bdirect linking, since Drepper doesn't want
it.  He doesn't have absolute control over binutils though; so if we're
lucky once Meeks gets that working correctly it might actually go in
... we'd still need a patched glibc...

Heh.. too bad it doesn't work perfectly as-is, or I'd advocate the
Ubuntu devs pushing that into Edgy+1 too.  It can be done; but it'll
take work, too much maintenance.

Ehh I'll let them decide.  /me loads some information into the spec so
the devs can make their own decision.

Looks like a hack.  Look into preload.

    new problems waiting out there.
