I am not entirely sure this would be a good idea.  I work on a Mac as  
well (PowerPC) and never encountered this issue.  Maybe that's  
because I don't use the Python installation that comes with MacOSX  
but rather installed my own Python using DarwinPorts.  If someone  
could give me more details on how to reproduce this, I would be  
willing to test if I can reproduce this problem on my setup as well.   
But from what I understand reading this thread, it is a problem  
related to Apple's Python distribution or MacPython, but might not  
apply to other distributions or a Python installation from source.

With kind regards,
