> The 'block_manager_blocks_open_writing' metric is showing tens of thousands of blocks open for write on my tservers in a test cluster. That seems incorrect to me, since we should only have blocks open in the middle of a flush. Perhaps the metric is wrong, or perhaps we are somehow leaking open blocks.
