Wouldn't you still be able to get stale data in case of a temporary network
failure?

The case I specifically want to optimize is relatively simple: a gallery of
images where we construct the page based on cached query results. Since
they're for viewing only, it won't matter if they're up to 10 minutes out of
date in the worst case.

As long as I don't base writes to the DB on cached entries, I should be in a
safe area, right?
