Hi Willy,
It seems that the loop will be only excuted once.
The related codes as below(src/stream_interface.c):
> static int si_conn_send_loop(struct connection *conn)
> {
> ...

> ret = conn->xprt->snd_buf(conn, chn->buf, send_flag);
> if (ret <= 0)
> break;
>
> chn->flags |= CF_WRITE_PARTIAL;
>
> if (!chn->buf->o) {
> ...
> }

Since there is a 'break' with no condition in the last line of while
loop, the loop will
be only excuted once. It just looks like a 'if' as below:
> - while (!(conn->flags & (CO_FL_ERROR | CO_FL_SOCK_WR_SH | ...))) {
> + if (!(conn->flags & (CO_FL_ERROR | CO_FL_SOCK_WR_SH | ...))) {
