This is a decorator which will gets Django to try the cache before computing the result of a function. It automatically builds the cache key as a hash of the function name and inputs, and allows you to set whatever timeout you want.
The code is Django 1.4 version of code based on the [Django 1.3 snippet](http://djangosnippets.org/snippets/2593/) that speeds up Django's admin pages with postgres back-end for big tables (> few hundred thousands of records).
Just put it in your python path and add it into MIDDLEWARE_CLASSES. I know that there are a couple of snippets on this site that do something similar to this, but none of them quite suited me. I wanted something that would indent and space the SQL so that I could differentiate it from the other output from the development server. Also, I wanted something that would output total query execution time, which my solution does. I just hope that it's useful for someone else, too! UPDATE: Now this should no longer get upset when running it on windows.
