I'm not sure it's really due to a race condition. All requests are coming from he same page. Those requests for jpeg images which are served through send_file are called one after another and still, they are changing the session cookie all the time.
On the other hand, the problem only occurs when loading the page for the first time after I cleared all cookies client-side. And btw, I set cookie :domain => ".vidmap.de" in production environment. I'm perplexed.
