The patch simplifies the multicast code in ipoib, and the serialization in the 
multicast module is simple enough that we should be able to have a fair amount 
of confidence that races are avoided.  (It's not like I'm biased or anything.) 
The code just needs more testing.

Going forward, it makes more sense to have ipoib use the multicast module.  The 
only question to me is when that conversion takes place.  I'm also worried about 
having to try to regenerate the patch after other changes go into the code.
