0004  *
0005  *  This task initializes the signal catcher, sends the first signal
0006  *  if running on the first node, and loops while waiting for signals.
0007  *
0008  *  NOTE: The signal catcher is not reentrant and hence RTEMS_NO_ASR must
0009  *        be a part of its execution mode.
0010  *
0011  *  Input parameters:
0012  *    argument - task argument
0013  *
0014  *  Output parameters:  NONE
