Sure, I agree with the goal, no question about that.  I was just thinking about
getting there in two steps (with no delay between them implied) which might
have been at least easier to review.  Also bisecting would be easier that way
if we later suspect that there might have been an unexpected change of
behaviour after all, possibly related to the migration to glib sync primitives.

Anyway, the work has been pretty much done already so the point seems moot.
