<pre>This happens sometimes with several layout tests and unit tests in the GTK+ port. It doesn't always happen because it depends on how sockets are closed, and the state of the threads. The problem is that we are not handling the case when the read fails because we closed the connection. In that case we log the error and call Connection::connectionDidClose(). But it was connection didClose() the one closing the socket. So, in this particular case is not an error but a normal termination, and we shouldn't try to close the connection again. Something similar can happen while sending a message, and we get a broken pipe error, but in that case we are only showing the error, so it's harmless.
