To avoid busy waiting....we use block and wakeup functions in our definition of wait() and signal()

but its mentioned in Galwin that still we have not been able to eliminate busy waiting completely....

"we have just removed busy waiting from entry to the critical section....futhermore we have limited busy waiting to only the critical sections of Wait() and Signal() operations...and these sections are short...thus critical section is alsmost never occupied and busy waiting occurs rarely..."

what do they mean by this...?
