It is a symmetric bell-shaped distribution which can be used to represent a very large number things from every-day life. It has some very useful statistical properties.
No, a busy wait cannot probably be avoided altogether. In a uniprocessor system, one could inhibit interrupts during wait()andsignal()operations in semaphores, but that is not possible in multiprocessor systems. In fact, a busy wait (orspinlock), can be useful, especially in multiprocessor systems, when the wait is expected to be short (as withwait()andsignal()), because no context switch is required when a process must wait on the lock.

Usually it's not what's being summarised (in this case, money) it's how the stuff that's being summarised is distributed that matters. If the distribution is symmetric and the danger of there being large outliers is small then the mean could be a good choice. The range is useful for quite different purposes than the other three statistics.
