More seriously Stephen, if the infrastructure is clean, and well
tested on a relative simple case (UDP), it can then be deployed on a
much more interesting protocol : TCP

I'm really looking forward to someone finally tackling that problem :)

The moment we switch to RCU, we have to accept the pain of really
understand what we did. Details are scary yes.

Agreed.
