2.6.29-rc contains UDP receive improvements (lockless)
Problem is multicast handling was not yet updated, but could be :)

When will that happen?

When proven necessary :)

Kenny problem is about scheduling storm. The extra spin_lock() in UDP
multicast receive is not a problem.

My tests here show that 2.6.29-rc5 still looses ~5usec vs. 2.6.22 via
UDP. This would fix a regression.....
