Having a log at the very begining of "our" code helped us find issues with
App-Engine's dispatcher, where we could clearly see in the logs that "our" code
started many seconds after the request came in.
We now suspect there is something similar going on after the end of "our" code
- where the reply is sent back many seconds after our code finished running.
To make sure - we add a log statement at the very last line of "our" code, so
we know exactly when it ended.
