KeepAliveTimeout option causes multiple connections to be created and orphaned

[jotto]

If you're blocking on ReadMessage(), while the goroutine for KeepAliveTimeout fires a closeAndReconnect, the ReadMessage will fire a second closeAndReconnect. This causes more and more connections to be created and orphaned.

The root cause of the bug is simultaneous running of the connect goroutines.
Please take a look at #34 - should be fixed there.
