mod_python: How to make a single object available to all instances?

[Trond]

I have a dictionary which is ca 40mb in size. I need this dict to be
available for each apache/mod_python thread. But since it is so big, I
cannot allow each thread to retain a copy of the dict, and it takes
too much time to load the file from db/hd. So I wonder if there is any
methods for making the dictionary "global" for all threads, like an
enviromental variable or something.
