There are a few other questions. Let's say config.py contains a variable 
like 'font' that is a user set preference or a calibration value 
calculated by A to keep with the thread title. Assuming both scripts are 
running, how does the change get propagated to B after it is set in A and 
written to the shared file? Is there a mechanism to allow both scripts to 
make updates?

The easy way out is to assume the changes will be picked up when the 
scripts are restarted but this is not always acceptable.
