I'll probably rewrite this code a little, to instead just allocate a 
chunk of memory, and then try to find a somewhat optimal size to use, 
based on the terminal size, and the size of the memory. So that, if you 
only have 80 columns, you should be able to have more rows than if you 
have 132 columns... Later today maybe.
