Second commit contains:

  1. bug fix in DelegatingScheduler#schedule: (delay == 0) → (delay <= 0)

  2. fix, if user's executor is actually commonPool() without parallelism. Similar to CompletableFuture.screenExecutor

  3. Use less memory: don't capture variable if executor is commonPool (Lambda can access it without capturing through static field.
