I'm currently using Django, and I can understand where they are coming from. The sheer amount of code that a simple request has to go through to receive an answer is staggering sometimes, such as 18 line tracebacks just to identify an authentication problem...
My own projects are not yet large enough to have this cause an issue, but I can see where something the size of Reddit would indeed have issues that even the most aggressive caching can't resolve.
