Hmm... sorry: I'm catching up with some mail backlog and didn't read
carefully.  I noticed too late that I misread: your message was not in
reply to my last suggestion but to some earlier discussion.  So, please
disregard the above text.

I'll finish reading my mail before replying further.

I think the following part of my answer is still correct, tho maybe
out-of-date with subsequent discussion I'm about to discover.
