I do consider it a bug.
If it's backpatchable or not depends on the patch complexity, imo.
Given that the solution is creating a separate connection for it, I
think it should *not* be applied to 1.10, because it's a large
problem. If someone had corrected my diagnosis and found a
lower-impact way, then it could've been.
The patch looks surprisingly simple :-) But I can't see why it
wouldn't be correct - looks good to me.
