Note that even active defrag won't be able to handle the case where you want have lots of big pages, consituting a large percentage of available memory.
Not unless you think I am crazy enough to do garbage collection on kernel data structures (repeat after me: "garbage collection is stupid, slow, bad for caches, and only for people who cannot count").
Also, I think the jury (ie Andrew) is still out on whether rmap is worth it.
