2.1 terabytes...wow.  but think about it this way: if you did manage
to build such a beast, a route cache would not be needed, as route
lookups would all be O(1).  :)

actually...if you *did* manage such a thing, you could get the memory
usage down a lot, since you'd just need to store next hop for each ip
address, and not so much stuff about linked lists and stuff.
