two questions about the code

[hellasmoon]

1. in main function, after passing the tcp_server to all the worker threads, why calling uv_run again right after uv_close((uv_handle_t *)&tcp_server, NULL)? (keyless.c, line 1015, master branch)

2. in function flatten_operation, why should we pad the operation to KSSL_PAD_TO + KSSL_ITEM_HEADER_SIZE bytes?
