    Actually, Linux *does* have a 2 GB (2^31-1 bytes) filesize limit in
    the current incarnation. For one thing, the file length field in the
    ext2 inode is 32 bits.

    There has been a lot of talk about supporting a new set of 64-bit
    system calls and I think some of the latest experimental kernels do
    support them.
