Thanks a lot for the explanation. I don't think I'm going write patches
and reason about it. We were just looking for the best way to safely
flush maps in multipath-tools, and I'd considered deferred remove as
one option, which it most likely is not. Anyway, I like to understand
why thinks are the way they are, so thanks again.

Cheers,
