 * control should be the same as never calling suspend in the first place.
 *
 * If the control is for a local transaction then it is simple to recreate
 * the hierarchy. Otherwise we rely upon the PropagationContext to recreate
 * it.
 *
 * If this control is a "proxy" then create a new proxy instance, so we can
 * delete proxies whenever suspend is called.
 *
 * Should check if "new" transaction is not actually the current one anyway.
 * If so, just return. The spec. doesn't mention what to do in this case, so
 * for now we go to the overhead of the work regardless.
