Modulo the whole swap-deadlock thing, of course :) and things might start
getting a bit collisional eventually: that nice fast bus *is* shared,

(In fact the possibility of deadlock is present whenever you have
writable mmap()ings on networked storage, but it's rare to have very
large writable mappings on such devices.)
