    That's what I initially proposed. However, as Scott Olson pointed
    out, there's already a fix for this:

    http://lkml.org/lkml/2009/8/19/84
    http://patchwork.kernel.org/patch/42564/

    which uses still-non-portable /bin/echo.

    (I wish I knew about it a week before now - it wasn't a pleasant week for me).

    Still an interesting result. I can understand if it failed
    for systems with smaller amounts of memory, -- nope, it fails
    with Celeron on a 64Mb system, but works on the same system
    if I replace the CPU to a real PIII... Fun.
