Right. Same here. System python barfs on the 2nd example, 
source-compiled python doesn't for me...

I do think it's worth stressing that if you're running Zope, you should 
at least check that the two examples don't barf on your machine.

I'm sure there are lots of people out there using system builds of 
python, and it looks like at least the stable debian and ubuntu builds 
are vulnerable...
