There are several ways to do this.
Simplest if you are sleeping for periods is simply to re-read
the config after every wake-up.
Other options incliude using select() I think select will
work for files so if anything changes on the watched file
select will run its code.

select can be used instead of the sleep to only run the code
when an interesting event happens - provided your events are
detectable by select of course!.
The twisted framework should offer some other options too,
but I've never used twisted so am no expert.
