      The findOne below gets a "readConcern level snapshot is only valid in multi-statement transactions" even though it is in a transaction.

          ses = db.getMongo().startSession()
    dbs = ses.getDatabase("test")
    printjson(dbs.createCollection("c", {writeConcern: {w: "majority"}}))
    printjson(ses.startTransaction())
    printjson(dbs.c.findOne({$where: "sleep(2000)"}))
