No luck. I suppose one theory that could link both failure modes
would a buffer overrun, where in the non-shared case it trashes a
pointer that is later dereferenced, and in the shared case it writes
past the end of allocated 4KB pages and corrupts the intrusive btree
that lives in spare pages to track available space.
