Got it. It's a bug in the cursor recovery code that I added to
support mirror propagation. It's basically saying: "HEY MATT! YOU
FORGOT TO CALL hammer_cursor_deleted_element() SOMEWHERE!".
And indeed, that is what happened. I call it properly when an
element is deleted from a leaf in the B-Tree, but not when a
leaf becomes empty and is deleted from its parent internal node.
So cursors sitting in deadlock recovery on that internal node
were not being updated.
I'll commit a fix today, soon as I track down the bug Michael's
CR program revealed.
