Re: Reading large files using Nim

@jlp965 Even the blocks that are not "asked for" use up virtual address space. 
You can already see that in the api of memfiles. You get a pointer and a size. 
You don't get blocks that you then can put manually at an address you like. The 
memory mapped file uses one continuous block of memory in the size of the file, 
and there is little you can do about it.
