Visible variables are not changed by other threads during serial execution in either node or Erlang. But races in node can arise in terms of values changing unpredictably while before a callback is executed in node. In Erlang values can change when a process responds to another message, before processing a particular message. This seems like a race too. In either case the races are better contained in either node or Erlang than they are in more liberal models like the java or .net ones.
