The loop should be:
do { rc = ngx_http_output_filter(self->r, &out);
self->r->connection->write->ready = 1;
} while (rc == NGX_AGAIN);
In usual processing event->ready is set by event module (kqueue/epoll/etc).
Ok, this solves the problem, thanks! Now ngx_http_output_filter returns NGX_ERROR when the client closes the connection.
There is only one minor problem. When I send a SIGINT signal to nginx during a blocking write operation, the termination is not "clean":

Not a big problem, however.
