Segfault while passing arrays as argument to actors

[albertnetymk]

class Agent {
  def init() : void {
    ();
  }

  def pass_arr(arr:[int]) : void {
    print arr[0];
  }

}

class Main {
  def main() : void {
    let
      l = 1*1000*1000
      arr = new [int](l)
      a = new Agent()
    in {
      a.pass_arr(arr);
    }
  }
}

After disabling GC for each actor, the above program still crashes. It's related to #116, but, maybe, it's a different bug.

Put gc_done(&actor->gc); in pony_create before return. It's already fixed in upstream.
