Oh that makes more sense.

In that case I don't see the big need in moving the flows/sockets
after establishment.  After all process migration should be rare,
so if it does occur then it's OK for the existing sockets to stay
on their original queue.

I'm curious about what the limit on the number of flows is though.
Because when you go above that limit performance will magically
suck :)
