That's also unexpected.  There should be only one.

Please show a reproduction recipe, as I didn't know this is possible.

If the problem is with the messages, it can be easily solved by adding
some optional feature.  But I understand there are more urgent issues,
so let's discuss those first, okay?

Feel free to submit patches for that, and thanks.  (But didn't you
just complain about one speller process per buffer?)
