    I agree it'd be a lot simpler to handle 32bit user on 64bit kernel if we
    can clear it unconditionally (otherwise we've to trap getfl with a
    ia32 wrapper) but I'm afraid the api may break if we clear that bit
    unconditionally. I can't tell you for sure by memory though because the
    last time I worked on this was one year and half ago and this is really
    a matter of API. We should ask the glibc people for another confirmation
    before choosing if to clear it only in 64bit archs or in 32bit too.
