   Yea to sum up, these are the options:
   
   1.  Implement a counter  for each ClientPool, that is incremented at beginning of ClientPool::run() call, and decremented at the end.  The close() thread will block until counter is 0.
   
   2.  Implement a retry mechanism in CachedClientPool::run(), which will call call clientPool() again if we hit a closed client.
