you really should never alter $r->status, as apache uses it for internal

except for registry scripts :)  for registry scripts $r->status is a hack
way of telling registry to 'return REDIRECT' since registry itself can't
trust the value of the cgi script's return code (since it's an emulation
layer).  beneath the hood, however, registry discards the $r->status setting
and sets it back to whatever it was before registry ran:

    # handlers shouldn't set $r->status but return it, so we reset the
    # status after running it
    my $old_status = $self->{REQ}->status;
    my $rc = $self->run;
    my $new_status = $self->{REQ}->status($old_status);
    return ($rc == Apache2::Const::OK && $old_status != $new_status)
        ? $new_status
        : $rc;
