trajectory graphs

19.    In theory, resource trajectory graphs could be used to avoid deadlocks. By clever scheduling, the operating system could avoid unsafe regions. Is there a practical  way of actually doing this?

20.    Can a system be in a state that is neither deadlocked nor safe? If so, give an  example. If not, prove that all states are either deadlocked or safe.

21.    Take a careful look at Fig. 6-11(b). If D asks for one more unit, does this lead to a safe state or an unsafe one? What if the request came from C instead of D ?

22.    A system has two processes and three identical resources. Each process needs a maxi- mum of two resources. Is deadlock possible? Explain your answer
