I'd like to understand better what exactly breaks on Mandrake.  
Certainly, I've never had a problem on various Redhati.  AFAIK, that 
argument is mostly for process listings, e.g. ps and doesn't have any 
semantic value.

As you can tell by the comment just preceding these lines, I've thought 
about different values for argv0 and settled on 'qrunner' because it 
looks the best to me when I do a ps listing.  On my RH9 system, if I 
use the empty string, then it eats arg1.  So I'd consider using 
mm_cfg.PYTHON, but then the command line gets pretty long.  'qrunner' 
just looks the best so I'm disinclined to change that unless it fixes a 
real bug.
