Hi Xuneng,

Thanks for tying the threads together.
When Álvaro raised the possible connection back in May,
I concluded these were independent fixes for different problems,
even though both already touch ResolveRecoveryConflictWithBufferPin().

That still holds, but with the deadlock-detector fix now ready for commit
and heading to the back branches,
the two reworkings of that function will collide.
So I agree it should go in first and this patch should rebase on top.
