Okay, the outstandingOps race was easy to resolve, I'm changing refresh()
to do this:
```
private void refresh() throws Exception
{
// Push an extra op so that a race between refreshData() response and
// refreshChildren() can't cause the outstanding ops to drop to zero.
try {
outstandingOps.incrementAndGet();
refreshData();
refreshChildren();
} finally {
outstandingOps.decrementAndGet();
}
}
```
With this I can add a Thread.sleep() at that start of refreshChildren() and
there's no problem.
