I think the important effect of the fix is to encourage automatic code 
verification both by the group that found this bug and by and others. 
Future verifier developers can check their code by trying to verify the 
fixed code.

The C half of the CPython code base has been improved by responding to 
issues raised by the Coverity checker.  I hope we can get free code 
reviews both of C and Python code from others.
