> I would like to be able to determine the number of threads waiting to obtain an object from the pool for monitoring purposes. This would be most applicable when the WHEN_EXHAUSTED_BLOCK option is used. I propose the following method:
> /**
> * Return the number of threads currently waiting for an object from this pool.
> *
> * @return the number of threads currently waiting for an object from this pool
> */
> public synchronized int getNumWaiters() {
> return _allocateQueue.size();
> }
