My question is little different. Each Process Pi, i = 1....9 is coded as follows repeat P(mutex) {Critical section} V(mutex) forever The code for P10 is identical except it uses V(mutex) in place of P(mutex). What is the ... you can signal semaphore from any other thread (or process), so semaphores are more suitable for some synchronization problems like producer-consumer."
