Re: patch to randomize mmap offsets

    Randomizing mmap offsets that much will fragment user virtual memory
    and cause the program to run out of space if it uses mmap() heavily.
    I really dislike the concept.

I have to agree with Simon, doing as you suggest will reduce the effectiveness of the concept(maybe to the point where its not worth doing at all?) Obviously we shouldn't be wasteful but the benefit of random distrobution here outweighs the memory costs.
