Updating a module level shared dictionary

[Vishal Rana]

Hi,

A module level dictionary 'd' and is accessed by different threads/requests
in a django web application. I need to update 'd' every minute with a new
data and the process takes about 5 seconds.

What could be best solution where I want the users to get either the old
value or the new and nothing in between.

I can think of a solution where a temp dictionary is constructed with a new
data and assigned to 'd' but now sure how this works!

Appreciate your ideas.

Thanks
