here I need to add that if your software indeed does load that many
images into the memory
you should look for something better. by doing so you will have a severe
I/O bottleneck;
make sure data is loaded partially by the software. only time you need
that much memory is
when you actually have that much *modified* data in memory or as a cache
for a really
high-performance image store server. any other valid cases are exotic.
