This will stop being a problem when we actually have btrees, but for now the fragmentation caused by byte-level syncs was easily enough to overflow an mdir when cache size is big. A smaller cache size is also nicer for debugging, since smaller cache sizes results in data getting flushed to disk earlier, which is easier to inspect than in-device buffers. And a 16-byte cache still provides decent test coverage over cache interactions. --- Also dropped inline_size to block_size/8. I realized while debugging that opened shrubs take up additional space until we sync, so we need to expect up to 2 temporary copies of shrubs when writing files.
