// minimal test to check handling of batch size when explain info is requested
// expected behavior is to return explain.n = total number of documents matching query
// batch size is also tested in another smoke test jstest/explain1.js but that test
// also covers the use of an indexed collection and includes a couple of test cases
// using limit()
t = db.explain_batch_size;
