Right, the above assumes only one cache_dir.

With more than one, new swap files are allocated from the directory
which has the largest percent of free space. e.g.:

        static int
        storeDirMapAllocate(void)
        {
            int dirn = storeMostFreeSwapDir();
            SwapDir *SD = &Config.cacheSwap.swapDirs[dirn];
            int filn = file_map_allocate(SD->map, SD->suggest);
            SD->suggest = filn + 1;
            return (dirn << SWAP_DIR_SHIFT) | (filn & SWAP_FILE_MASK);
        }

In other words, Stew's changes don't affect the cache_dir load
balancing.
