Re: settings file being imported four times

Hi Tomas,

If you're using Django 1.3, and you're using the development server
(which it looks like you are), then yes, it's normal. See:

http://blog.dscpl.com.au/2010/03/improved-wsgi-script-for-use-with.html

for an excellent explanation of what is going on.

If you're using Django 1.4, you should only be seeing 2 imports; one
of the imports mentioned in Graham's article has been cleared out.

Yours,
Russ Magee %-)
