    Its not being truncated at 255 characters, its being truncated at the
    first space. This is coming out of parse_args, which dumps '\0's into
    the command_line as it rips it apart. We now only have one copy of the
    command line (in x86_64) instead of two, so we now expose this trashed
    copy in /proc/cmdline.
