Comment 7 for bug 849071

This is actually very good. Gustavo understands the idea. He may not
completely agree with the implementation but the idea is out there and it is
a good one.

Gustavo, I understand your concern about the implementation. Would you
then suggest a more feasible way of implementing or accomplishing this?

Thanks,

Juan
