Try starting the interpreter with python -u xxx.py (-u = unbuffered) but I  
don't really think this might be the cause. Are you sure the code actually  
says sys.stdout.flush() and not sys.stdout.flush?

Usually written as:
sys.stdout.write("%-30s" % self.name)

And instead of:

   if xxx is True:
     ...

use:

   if xxx:
     ...

I don't think so... What's your platform/OS?
Try to post a minimal example showing the problem - copy & paste it, don't  
retype. Maybe in the process of reducing your code to find the minimal  
example, you find the problem yourself.

Are you aware of the existing framework for unit tests? the unittest  
module?
