Comment (by Zbyszek_Szmek):

 Two simple patches to explore the two possibilites: in-memory or on-disk.
 On my memory-starved machine (Celeron 1300 MHz, 300MB RAM) in-memory is
 slower than on-disk.
 To save three arrays (zeros(1000x1000), ones(1000x1000), rand(1000x1000)),
 it takes ~1.05s on-disk, and ~1.2 in-mem.
