Pavlin's fix to a bug where iperf end-time would become a large number after a link is cut. It
would only happen with sampling. When the link is cut a packet does not arrive for a long time
say over 10 seconds. Reporter_condprintstats is not getting called until a packet arrives.
The while loop keeps incrementing at 0.1s increments and so after 100 samples overruns the
buffer because I failed to put a check.
