It does say, however, that it's fine as long as the free memory isn't REALLY low. It did get down to 13MB though, as I said. So now I understand that it's alright for the free memory to be low. I don't understand how the inactive, cache, and buffered memory are used though. When a process uses up all the free memory, does it then use some from inactive, or does it use swap?
