Igor, do you thing that setting temporarily the socket to blocking mode 
can be a solution?

     out.buf = b;
     out.next = NULL;

     b->pos = data;
     b->last = data + len;

     b->memory = 1;
     b->flush = 1;

     ngx_blocking(self->r->connection->fd);
     rc = ngx_http_output_filter(self->r, &out);
     ngx_nonblocking(self->r->connection->fd);


I have done some tests and it seems to work.



Thanks   Manlio Perillo
