In a normal mod_tile setup, this would mean that the next time someone 
requests that area, the tile will be rendered again, and again, and 
again, each time producing (after a series of database queries) an empty 
tile. Compared to that, the cost of having a 116 byte file lying around 
is rather small!

Bye
Frederik
