Have you considered using ipython as your REPL? I use ipython and in my profile, I have the following setting. This enables auto-reload and it works almost all the time.

Here is the option I have in my profile file. You can run this command inside the ipython session as well:

%autoreload 2

The times I have seen auto-reload fail is when there is lot of class creation magic going on or while dealing with global connection objects which sql alchemy might be creating. But, other than that it works very nicely.
