as one of the zillion things I've never got around to fixing anywhere,
rate limiting mcast and dropping packets either in mac80211 or in
babel would be good.

babel could possibly be sane about it by using it's timestamping
facilities. (I ran across this babelweb pic from my old c.h.i.p + rtod
experience, which cracked 16sec of delay in the mcast queue:
