mod_limitipconn works at the request level, so won't help with
slowloris-style attacks.  Same goes for mod_evasive - someone
posted "mod_evasive doesn't help" on users@, and that'll be why.

I'm not sure whether any of the traffic-management modules
work on connections (anyone know)?  If so, then yes, we could
just point to them as a fix until we produce something better
than mod_noloris.
