I forgot to mention that the OS itself or other processes may be using a 
lot of memory. So, just because you have 2GB, that does not mean you can 
access all of that at once. I would guess that 25% of memory is in 
constant use by the OS. So, do your IO/reads in smaller chunks similar 
to the example I gave earlier.
