That depends on what you want. If you want the appended elements not to
be default-initialized because you overwrite the element yourself later
or you don't initialize it at all because you want partitially complete
pages which arent assigned to phyisical memory (unter Linux these pages
arent even reseved from swap with overcommitting) my ndi_t union is the
right thing.
The class only works if the encapsulated type has a trivial destructor
which is restricted by a concept to prevent to do the wrong things with
my union.
