Ah I did. I wasn't aware of it, because the mail doesn't have the
in-reply-to header set such that my MUA doesn't sort it to the patch
mail.

I saw this mail now. Let me note that it's intransparent for me how your
Sob line was added to the patch. The mail says the patch was queued,
does that mean it's about to be applied and will appear in next soon? Or
is it only queued to be looked at? (I assume the former.)

Best regards
Uwe
