    Well, it's an extension for sure, but a backward compatible one. It
    should not affect any correct existing application--i.e., one that
    checks it's return status--except maybe the odd test program that needs
    to be updated to handle the new semantics. We're allowed to extend APIs
    as long as we don't break correct applications, right?

    I mean, it's not like it's a new argument or such.
