The issue is that what to do when a receiver goes deaf is a policy
issue.
Something all these protocols alredy recognize and have done for years.
The real issue for AF_BUS versus the current slow AF_UNIX approach is
that you really need to know *who* is blocked up.
That's no different to UDP multicast and needing to know how errored the
frame.
And the policy on what to do about such UDP multicast errors is in
userspace, which is precisely my point.
