    Arne was complaining about the space cache having mismatching generation
    numbers when debugging a deadlock.  This is because we can run out of space
    in our preallocated range for our space cache if you have a pretty
    fragmented amount of space in your pinned space.  So just increase the
    amount of space we preallocate for space cache so we can be sure to have
    enough space.  This will only really affect data ranges since their the only
    chunks that end up larger than 256MB.  Thanks,
