Well, this means that estimate_ipcp_clone_size_and_time returns a
negative size growth estimate. The function is basically inlining
heuristics with special interface so perhaps such mishaps are to be
expected and I should take care even of negative values (PR 51362 was
about this function returning zero size growth estimates). Or are
they not, Honza?
