OMG. Great hack =)

David, thank you very much!

I'm not sure that I will implement this solution, because I don't
understand all the magic behind the code that should do the trick.
Hope it will be solved in Devel::Cover and I will be able just to use
`cover` without understanding all the secrets behind it.
