Activating a virtual environment also changes a couple of other things, but this is one of the most important things it does.

        // all services were NEW when it was called, and this has already been verified above, so we
        // don't propagate the exception.

**Additional context**

   * thus a motivated caller may be able to expose the reference to another thread that would then
   * call cancel() and be unable to cancel the delegate.
   * There are a number of ways to solve this, none of which are very pretty, and it is currently
   * believed to be a purely theoretical problem (since the other actions should supply sufficient
   * write-barriers).
