Server Instance Life time

This was always an issue since the beginning of GAE, with people suggesting fake requests or cron jobs to keep an instance alive.

I am following the issue since the very beginning and although I do not have indisputable numbers to share here there is one thing I can tell for sure the average timeout has increased quite a lot since the early days and currently is satisfactory to the extend that any application with reasonable hits, can expect to almost always be served from a hot instance.
