So, if i remove all data i've not used in the last, let's say, 30 seconds, it 
should work?
This sounds strange to me... i'd prefer to fill the ram till there is space 
available and remove unused data when i run out of space, this should improve 
the game performance avoiding all the load/unload work...
Is this policy SO bad?

How can i know if i *NEED* to do this?
I've evaluated that the program may reach a peak of 80 Mb of RAM usage.
Maybe i should finish it to get a better idea of the requirements?

Seems interesting, i'll take a look.



Thank you everyone!
