    How about reducing the number of synchronizations of batchesSent by
    combining the get() and the addAndGet() in the loop body:
    
    public synchronized void waitForSendComplete() {
      int waitForBatches = batchesSet.get();
      while(waitForBatches != 0) {
        try {
          wait.acquire(waitForBatches);
          waitForBatches = batchesSent.addAndGet(-1 * waitForBatches);
        } catch (InterruptedException e) {
          logger.warn("Interrupted while waiting for send complete. Continuing to wait.",
e);
        }
      }
    
    And now that you're continuing to wait in a loop, we don't need the TODO
    anymore.
