Data race in middlewares

When running go test -race in one of my projects I detected a few data races in gentleman's middleware code. Just to make sure, I ran go run -race _examples/goroutines/goroutines.go and got the output below.
I can't have a closer look right now, but I will as soon as I can. Meanwhile, if someone knows anything bout this, please let me know. Thanks :)
