Er, no, that's not what is going to happen.  Compute the space to
hold the databases for 2^36 keyblocks.  The 0x64 subspace is held
in two 32MB databases, and for speed's sake, it's best if those
can be held in memory.  There's no way they can do this with the
entire keyspace.  For efficiency's sake, they want to put the 0x64
keyspace to bed, and have it completely done so that it can all
be put out on mass off-line storage.
