Sorry to reply to myself, but I noticed when using httperf I still got
one or two messages (literally, it was very much reduced); the first
patch misses the fact there is also a race between 'lost' being
calculated and the timer interrupt possibly catching jiffies up to
wall_jiffies.  I also added a comment as I get easily confused.

The attached patch lets me run httperf repeatedly with none of these
warnings, though there still might be a better way to do it.
