My program counted things. Sometimes the count was right, sometimes it was off by a few, and there was no pattern I could see. The code looked fine. It was fine, as long as only one thing was running at a time. The trouble started when I added goroutines. If you’ve ever had a bug that only shows up “sometimes,” there’s a decent chance you’ve met the same problem.
