class mutex

[Prof. Peter Stoehr]

Hi out there,

there is a class mutex shipped with python. I've tried to use it to
syncronise two processes created with os.fork() and failed :-(
Looking at the source code of mutex.py I found out, that it is
implemented in pure python. Thus, it does not implement a real
mutex-object as a python code can be interrupted after each step of the
byte-code. 
Based on that, I have two questions:
1) Does python provide a real mutex object.
2) What is the use of the class mutex 

    Greeting
        Peter
