What they said is correct regardless of that though?
The point the article makes is that a 32GB file can be mmapped even if you only have 8GB of memory available - it wasn't talking about the address space. So the response is irrelevant even if technically correct

I don't think so.
Their post is basically:
>> It still works if the file doesn't fit in RAM
> No it doesn't.
Which is incorrect: it actually does work for files that don't fit in RAM. It doesn't work only for files that don't fit in the address space, which is not what the author claimed.
