/* the demo tests EDFACT with my Celeron 366 Mhz.
Aster1 meet all wcets and all deadlines
Aster2 miss all wcets but hits all the deadlines
Aster3 blocks on a semaphore so it miss all the deadlines and it accumulates
pending activations
Aster4 does 5 states:
1: is a cycle, long enough to cope a little more than 2 periods
2-5: like aster1, they meets all the wcet and deadlines
the debug pattern is something like
WDDEEeIeIeI
W wcet violated
D deadline miss event
E endcycle with automatic reactivation due to pending activations
e normal endcycle
I normal reactivation event
