On a synchronous send from the stream to an applet, if some data were sent, we must take care to wake the applet up. It is important because if everything was sent at this stage, there is no other chance to wake the applet up, mainly because SE_FL_WAIT_DATA flag is set on the applet's sedesc in sc_update_tx() at the end of process_stream(). This flag prevent any wakeup of the applet for a send event. It is not necessary for a mux because the mux stream is called when a syncrhonous send from the stream is performed. So it is reponsible to wake the mux connection if necessary. This patch must be backport to 3.0.
