Oh, interesting. Was that done for vfork(), or is it for something else? Some of the changes seem almost overly careful. Is this for prep-work porting to some odd environment that doesn't really have a MMU at all? There's nothing fundamentally wrong with allocating memory after fork().

But yes, it looks like it helps the vfork case.
