asynchronous timer events - how to?

[Helmut Jarausch]

Hi,

I'm using a web server (Karrigell) which is based on the asyncore module.
I'd like to be able to checkpoint some data (e.g. pickled dictionaries) to disk
from time to time.
For that I would need to setup a timer which calls a Python object/function when 
its time interval has expired. While this function is running I need access to 
the variables of the server.

Can this be done in a simple way?

Many thanks for a hint,
