Thanks for your quick reply, Ryan. I have found several postings on the Web that describe the same problem, namely, GetObjectById returning stale data. Here are two from StackOverflow:
http://stackoverflow.com/questions/26377347/inconsistent-fetch-from-google-app-engine-datastore http://stackoverflow.com/questions/22005349/appengine-jdo-with-multiple-server-instances-loses-transaction-updates-on-entiti Under the circumstances, I don't think it would be a good use of my time to make a demo app. It seems clear to me that the issue exists. Besides, the problem is so intermittent that a demo app is of very limited value. I would be perfectly happy with a statement of the kind, "GetObjectById() does not guarantee strong consistency, that's how it is, and here's what you do instead to get strongly consistent data." I just need to know what's going on.
