 Revision:    $Revision: 1.1.1.1 $
 Last update: $Date: 2002-09-02 09:37:48 $
 ------------

 Test Number 1:

 this test is a simple main() function with other 2 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

 task_nopreempt
 task_preempt
 task_create
 task_activate
 task_delay
 group_activate
 normal task termination (task_abort)
 normal system termination (sys_end)
 standard atexit functions (the keyboard...)
