Custom malloc/mmap for x86_64

[Daniel]

Thanks Mike,

That was exactly what I was looking for. It turns out that if I 
am to use wrappers I need to make sure my 
methods allow for a maximum of 6 arguments. So I need to 
do some re-structuring to my mmap calls. 
Once again, thanks for the quick reply to everyone here :)

Best,

Daniel
