can't connect to mongo using mongoose on Node 0.12 or io.js when zones are enabled

[aszs]

The following code appears to works on Node 0.10 but not on 0.12 or iojs 1.4.1:

require('zone').enable();
var mongoose = require('mongoose');

mongoose.connect("mongodb://127.0.0.1:27017/test", function(err) {
  console.log("connected to database:", err);
});

On Node 0.12.0 and iojs 1.4.1 the following error is thrown using the zone package from NPM:

connecting to database: [Error: connection closed]

The behavior is different when using the latest version of Zone on github, node aborts before calling the example callback:

net.js:806
    var req = new TCPConnectWrap();
              ^
