Just for record: diskless stations now _have_ possibility to
swap. Take a look at network block device (Documentation/nbd.html). It
can be used for swapping as is, but it _can_ deadlock.

PS: If you care about deadlock when someone hits your machine with
network trafic *real* hard, you'll have to apply big patch to network
layer which should make it rock solid.

Swapping over network is better :-). Anyway, we _should_ be able to
work completely without swap...
