Well, it's estimate_ipcp_clone_size_and_time that returns zero
estimated size growth. I find that quite strange, I'd never expect
the function to return that, I'd expect a new function clone to
certainly take up some space. Honza, should I handle the zero size
value or is that the bug that should be addressed?
