Show how priority inheritance can cause deadlock and also multiple blocking. For example, consider the following sequence (with 1 2): 1: Lock S1; Lock S2;

Show how priority inheritance can cause deadlock and also multiple blocking. For example, consider the following sequence (with τ1 τ2):

τ1: Lock S1; Lock S2; Unlock S2; Unlock S1

τ2: Lock S2; Lock S1; Unlock S1; Unlock S2

Here two tasks use two semaphores in a nested fashion but in reverse order.
