 Posix test 1:
29
 
30
   the main task create 4 tasks, J1, J2, J3, J4
31
     at t = 0.2 sec. it raise a signal to J1
32
     at t = 0.4 sec. it raise a signal to J2
33
     at t = 0.8 sec. it kill J4
34
 
35
   J1: it simply calls sigwait
36
 
37
   J2: it simply calls sigwaitinfo
38
 
39
   J3: it simply calls sigtimedwait with a timeout of 0.5 sec.
40
 
41
   J4: it simply calls sigtimedwait with a -long- timeout
42
       (J4 will be killed by main)
43
 
44
 non standard function used:
45
   cprintf
46
   sys_gettime
47
   keyboard stuffs
