It will be able to run when all freezable threads are frozen. > One thing I am very confused is, if all the other threads goes to > sleep,can this only one thread(assume only one thread marked itself as > unfreezable.) still works well? The question is rather theoretical, because there are some unfreezable threads in the system. In theory, such a thread can work well as long as it doesn't need to wait for another thread that is frozen.
