Yep.. its the same thing that happens if the pcb create fails
(we allocate with NOWAIT as well).

And in actuality this should not happen... if it does we are
getting near the limit of the number of associations (you
will see me often use the term association.. same thing
as connection) thats allowed. We drop before allocating
if we have hit this limit of course :-0
