sc_is_send_allowed() function is used to know if an applet is able to receive data from the stream. But this function was designed for applets using the channels buffer. It is not adapted to applets using their own buffers. when the SE_FL_WAIT_DATA flag is set, it means the applet is waiting for more data and should not be woken up without new data. For applets using channels buffer, just testing the flag is enough because process_stream() will remove if when more data will be available. For applets using their own buffers, it is more complicated. Some data may be blocked in the output channel buffer. In that case, and when the applet input buffer can receive daa, the applet can be woken up. This patch must be backported as far as 3.0 after a period of observation.
