      Description

      Better concurrent refinement statistics are needed in order to improve the control of the concurrent refinement threads and the mutator thread processing of dirty card buffers. We need estimated card logging rates rates and estimated logged card concurrent processing rates.

      Currently the nearest we have is DCQS::processed_buffers_mut, which is not at all sufficient. And once we have sufficient information, that buffer count should be replaced.
