 ------------

 Test Number 5:

 this test is a simple main() function with one other task

 This test has to be compiled with init1.c, that introduce 2 RR levels
 with a timeslice of 300us (!)

 This test can be useful to test functions like

 sigemptyset
 sigaddset
 hartik_deliver_pending_signals
 sys_end
 task_sigmask
 sigaction
 sigqueue
 task_signal
