Not really. You shouldn't depend on App Engine instances to stay alive since
we will tear them down and start them up as needed. What is it that you are
doing that you can't do with Memcache?

An alternate implementation could be to use Backends to maintain a long
lived data object cache, but this is arguably more expensive
engineering-wise than just using memcache.
