There are hacks to work around this --- for example, you can set up
large amounts of shared memory and map that on demand when you are
looking up your dataset.  However, it's simply not possible for user
space to refer to more than 3GB at once on Linux/Intel.  You *must* go
to a 64-bit architecture if you want more than that.

Cheers,
 Stephen
