Hmmm. The article from Chris you have linked does not mention the  
size of the mem segment you can allocate. Nevertheless - if you  
compile a 32 Bit binary, there is the limitation Brian mentioned.

You can easily simulate this with a small C program that allocates  
memory - if you compile it as 64 Bit binary - not problem, if you  
compile as 32 Bit - crash.
