i tried Allen's sample in Firebug, and someVar is accessible from
outside.
aWorker.someVar = "outside value";
console.info(aWorker.someVar); // "outside value"
Also works when a new instance of the class is assigned:
var x = new aWorker();
x.someVar = "outside value";
console.info(x.someVar); // "outside value"
