I am pretty sure, at least on linux, fork works with "copy on write" 
semantics. That is, stuff will be copied, but not before you actually 
write to it. So, read only stuff, like maps, textures, etc, will never be 
copied.

Before we'd usually say, there is a deep rumbling sound of penguins. Now
it's time to begin with: The earth is quaking, hell yeah the penguins are 
here!!
