      It is possible that a test sets the "cursorTimeoutMillis" server parameter to a small value and never resets it to the default value of 10 minutes. Running the run_check_repl_oplog.js check after one of these tests can cause the cursor on the oplog to time out. We should set the noCursorTimeout option on the oplog cursor to prevent it from timing out.
