Opening connection hangs indefinitely when connecting to wrong pipe name

[abrasaxdeity]

Run following code:

MySqlConnectionStringBuilder builder = new MySqlConnectionStringBuilder
{
	PipeName = "nonexistingpipe",
	ConnectionProtocol = MySqlConnectionProtocol.NamedPipe,
	Server = ".",
	ConnectionTimeout = 1
};

MySqlConnection conn = new MySqlConnection(builder.ConnectionString);

conn.Open();

Expected behavior: throws exception after 1 second
Actual behavior: hangs indefinitely on conn.Open()

Fixed in 0.64.1.
