/**
 * block_pool - An efficient allocator for blocks that don't need to be
 * resized or freed.
 *
 * block_pool allocates blocks by packing them into buffers, making the
 * overhead per block virtually zero.  Because of this, you cannot resize or
 * free individual blocks, but you can free the entire block_pool.
 *
 * The rationale behind block_pool is that talloc uses a lot of bytes per
 * block (48 on 32-bit, 80 on 64-bit).  Nevertheless, talloc is an excellent
 * tool for C programmers of all ages.  Because a block_pool is a talloc
 * context, it can be useful in talloc-based applications where many small
 * blocks need to be allocated.
 *
 * Example:
 *
 * #include <ccan/block_pool/block_pool.h>
 *
 * int main(void) {
 *      struct block_pool *bp = block_pool_new(NULL);
 *
 *      void *buffer = block_pool_alloc(bp, 4096);
 *      char *string = block_pool_strdup(bp, "A string");
 *
 *      int array[] = {0,1,1,2,3,5,8,13,21,34};
 *      int *array_copy = block_pool_memdup(bp, array, sizeof(array));
 *
 *	memset(buffer, 0xff, 4096);
 *	printf("string = %s\n", string);
 *	printf("array_copy[0] == %i\n", array_copy[0]);
 *      block_pool_free(bp);
 *    return 0;
 * }
