work channel in gmeasure.Experiment.Sample is not closed upon return

[davidhsingyuchen]

My understanding is that the goruotines will still be waiting on range work even after Example.Sample returns, and the fact that those goroutines are still referencing the work channel may further prevent the channel itself from being garbage collected. Please let me know if I'm missing anything, thanks!

...it just caught me these days leaking worker pools. Not that I'm not full of good intentions to not leak, yet ... well, you know...
