Summary
We seem to have a couple frequent flakes on GitHub that don't easily reproduce in my (fast) development environment. Today I decided to try the same thing on a slower machine (4x 1.5Ghz), and was able to reproduce the failures, which seem to be due to flags being reinitialized outside the lock (e.g. "before = 2, after = 0" on an only-incrementing counter must be a reinit).
Testing
5 runs of
go test -count 1000 ./internal/eventswith zero flakes. (about 25 minutes on the aforementioned machine)
