Do you really need such a large number of Ncells ? I think not. Try
starting R without specifying --nsize (and maybe even --vsize). In
1.2.0, R would automatically allocate more memory if the intial value
is not enough. But (as far as I know) it would not decrease the amount
of memory below the initial amount.
