We don't admit because we don't consider it a flaw.

If you're using Concurrent and runnables, you're sending jobs (the runnables) 
into a shared resource (the thread pool). Those jobs are expected to finish as 
fast as possible, which would preclude sleeping.

If you need to sleep, for whatever reason (and the only valid reason I've ever 
heard is polling hardware), you probably want a long-lived, dedicated thread. 
So not a thread pool.
