 Now our code is unaware that the `SecurityContext` is being propagated to the `Thread`, the `originalRunnable` is run, and the `SecurityContextHolder` is cleared out.
 In this example, the same user is being used to run each thread.
 What if we wanted to use the user from `SecurityContextHolder` (that is, the currently logged in-user) at the time we invoked `executor.execute(Runnable)` to process `originalRunnable`?
 You can do so by removing the `SecurityContext` argument from our `DelegatingSecurityContextExecutor` constructor:
