Avoid to crush node runtime by calling a constructor of native object without new

var nativemod = require("build/Release/mynativemod");
exports.Ctor = function () {
 return new nativemod.Ctor();
};

Generic constructor wrapper by bind with new

var WrapperCtor = function Ctor() {
 var args = [null].concat([].slice.call(arguments));
 var ctor = RawCtor.bind.apply(RawCtor, args);
 return new ctor;
};

var WrappedCtor = function Ctor(arg1, arg2) {
 var ctor = RawCtor.bind(null, arg1, arg2);
 return new ctor;
};
