patch to randomize mmap offsets

[Matthew Dillon]

:well, that's quite different.  randomizing mmap offsets gives a real random distribution over the whole userland address space.  allocating more and then offsetting within this allocation still gives a deterministic order of allocated memory locations, just the padding between those varies.

    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.
