I re-did the regression test. The system was not busy, cpu idle time is
86.7% and 97.1%. But Preempt.java failed, too. In fact, it doesn't fail,
however, it is blocked, for tens of minutes. so i have to stop its
execution. All you mentioned tests passed except Preempt.java.
I browsed the source code of preempt.java. Because of the
synchronization, there is no evidence to support preemptive scheduling.
