That sounds very reasonable to me!

I can't remember any issue that I've seen. I'll verify this at the end
of the week (until then I am pretty busy with my daytime job) and then
go with your suggestion.
Thanks again as always - your feedback is really appreciated!

Also thank you for commenting on the other patches. I'll take a closer
look at your feedback at the end of the week and send another version
of this series.


Best regards,
Martin
