Perhaps Monkyyy means that instead of appending the 0 on an 
existing string, it's better to allocate a new string for it 
instead, because you now must reallocate the original if you 
append to it?

FWIW, this is not what happens in phobos `toStringz`, it just 
appends without concern of this use case.
