Make the first sleep shorter, so numbers come up quicker, and scale the
delta so it is a rate-of-change instead of a meaningless number.
Avi Kivity (2):
kvm_stat: make the initial sleep shorter
kvm_stat: scale delta column to make it a rate

Scale the delta column by 1/sleeptime, so its units are
events per second.
