do the u.Debug = false in dht_test.go serve a purpose?

[jbenet]

e.g.

func TestPing(t *testing.T) {
    // t.Skip("skipping test to debug another")
    ctx := context.Background()
    u.Debug = false
    addrA, err := ma.NewMultiaddr("/ip4/127.0.0.1/tcp/2222")
    if err != nil {
        t.Fatal(err)
    }

No. Thats leftover from an age lost into the depths of time, when u.Debug controlled our logging output.
