thread safety

[dimzon]

Is there any proper way to compile JS function once and execute it in multiple threads?
I'm trying to catch function to variable - something like

        fn = (JSFunction) dynJS.evaluate(compilerScript,"\n;\n" +
                "(function(){return function(coffeeScriptSource, bare){return CoffeeScript.compile(coffeeScriptSource, {bare: !!bare});};})();" );

but invoking it in multiple threads produce exceptions

[mschwartz]

new java.lang.Thread(function() {
  while (1) {
    java.lang.Thread.sleep(1000);
   console.log('thread alive');
  }
});

what happens if you start two threads that access the same global variables and functions?

Rhino handles this proper.

Nation does not.

I choose Rhino because of this, every time.

I'd love to use dynjs in my projects, but it's not quite there yet.
