I'm not understanding these suggestions to restart the server. I'm
trying to watch time-varying data in the database back-end by pulling
a monitoring web page. Clearly the ORM knows the backing data has
changed, it issues a fresh query as part of the request/response
cycle. And much of the time, but not all of the time, that new data
actually shows up in the web page. I've done enough restarting and/or
re-installing as part of the dev cycle for this app to not believe
there's something corrupt in $APP/data that just needs deleting.
