It is unclear to me whether it makes much sense to report performance when 
things go wrong. At least when a one connection per client bench is run 
ISTM that it should not proceed, because the bench could not even start 
as prescribe. When connection break while the bench has already started, 
maybe it makes more sense to proceed, although I guess that maybe 
reattempting connections would make also sense in such case.

Hmmm. I agree that at least reporting that there was an issue is a good 
idea.

Indeed, I can only agree on this one.
