      The SharedBufferFragmentBuilder is designed to be a per-thread memory pool for allocating temporary buffers.

      It does so using an atomically reference counted SharedBuffer. This shows up around 2% of the time spent building an index.

      Since this builder is designed to be used in a single-threaded context, we should consider redesigning this builder to not share ownership if possible.
