Measurements are read from a channel and, in silent mode, the only output is printed after all measurements have been read. That is when the channel provided to fast.Measure() has been closed at the end of fast.Measure() and drained by the goroutine reading from the measurements. main() must wait for that goroutine that eventually prints the test result before exiting.

main() must wait for the goroutine that eventually prints the test result before exiting. Without this, a test executed with --silent sometimes doesn't show any output.
