Last time I brought up the whole swap over network bits I was pointed
towards the generic skb recycling work:

  http://lwn.net/Articles/332037/

as a means to pre-allocate memory, and it was suggested to simply pin
the few route-cache entries required to route these packets and
dis-allow swap packets to be fragmented (these last two avoid lots of
funny allocation cases in the network stack).
