I guess that this is the same scenario as a manual drive_mirror +
migrate test I have been doing.  I also get the "Co-routine re-entered
recursively" error message.

I've CCed you on an (unfinished) patch that solves the abort.  Please
test it and let me know!

Stefan, Yes!! This patch fixes the problem in our environment :) Thank you for digging into it and finding a solution. We'll patiently await a completed patch.
