    I would argue the same that the size of a buffer should never be able
    to be negative and the structure says this but the rest of the code
    does not. (Theoretically) if a negative size was asked for, then we'd
    actually try to allocate a large amount of memory for the buffer,
    possibly causing badness somewhere along the line.

    Any maybe we shouldn't make it too hard for archs with 2GB pages :)
    It'll probably happen in 20 years. :)
