That's interesting. Doesn't the ping update the the age table in cache, thus making sure that the continuation stays around? It seems like one ping per tab would keep each tab's original rendering context continuation alive. The ping would have to run more frequently to be useful in this regard, but then it would serve two purposes -- keeping the session alive, and keeping the continuation for that page near the top of the cache.
Or am I missing something? Again, I'm on 2.8 -- maybe this is different in 3.0.
