Why would you save anything?  If you're just parsing command-line
arguments, the settings are not persistent, are they?  Just
kept in memory for the duration of the current program.  If you
have multiple processes, each gets its own command line arguments
and thus its own in-memory values from globals.py. 

If you are actually interested in persistent, you'll need to 
expand on your original question, I think, because talking 
about "command line argument parsing" generally doesn't 
involve persistence, for most people.
