> The YAML parser already uses a BumpPtrAllocator for all its Nodes, but inside
> YAMLTraits we still use make_unique for HNodes. This results in lot of malloc
> traffic when parsing large or many YAML files.
> 
> Most HNode sub-classes can use a simple BumpPtrAllocator, but there are two
> sub-classes that need SpecificBumpPtrAllocators to call the proper destructor.
