[google-appengine] Re: Avoiding races when using memcache to back datastore queries

It probably doesn't surprise you that how NDB handles caching is more complicated (and sensible) than the docs summarise: Specifically, to avoid the problem you highlight, NDB puts sentinel '_LOCKED' value into memcache at certain points, to signal to other readers that an update is taking place
