Some caveats apply:

iirc with SDL you typically initialize and close down the different 
subsystems. With the GC finalizing surfaces will be freed after sdl 
shutdown, dunno if that's legal.

Also, sdl surfaces may take lots of space, so if possible I would free them 
when no longer in use. The GC may not collect at all, or late. But this may 
or may not be a problem.
