As an aside, what the hell is that err = 0 about? Before or after
that patch, that is - "let's make err zero, in case it had somehow
magically changed ceased to be so since if (err) bugger_off just above"?
.
err = 0 is no longer needed after if (err), I will send v2 patch to
remove the redundant code.
