 Revision:    $Revision: 1.4 $

 Last update: $Date: 2005-01-08 14:36:11 $

 ------------

 Posix test 1:

   the main task create 4 tasks, J1, J2, J3, J4

     at t = 0.2 sec. it raise a signal to J1

     at t = 0.4 sec. it raise a signal to J2

     at t = 0.8 sec. it kill J4

   J1: it simply calls sigwait

   J2: it simply calls sigwaitinfo

   J3: it simply calls sigtimedwait with a timeout of 0.5 sec.

   J4: it simply calls sigtimedwait with a -long- timeout

       (J4 will be killed by main)

 non standard function used:

   cprintf

   sys_gettime

   keyboard stuffs
