>          Components: Go - Library
>    Affects Versions: 0.10.0
>            Reporter: Zach Wasserman

> Run the following test with {{go test -race -run TestSocketConcurrency}}:
> {code}
> func TestSocketConcurrency(t *testing.T) {
>       host := "127.0.0.1"
>       port := 9090
>       addr := fmt.Sprintf("%s:%d", host, port)
>       socket := CreateServerSocket(t, addr)
>       go func() { socket.Listen() }()
>       go func() { socket.Interrupt() }()
> }
> {code}
> This will result in an error from the race detector. It looks like:
> {code}
> go test -v -race -run TestSocketConcurrency
> === RUN   TestSocketConcurrency
> --- PASS: TestSocketConcurrency (0.00s)
