If you just need to reuse the same array and only need to zero its elements

reallocation step).
Why is this “of course”? What’s the implementation of FillChar exactly? For all
I know it has to iterate over a range of bytes and this could be slower than
allocation of memory. Maybe some of the compiler people know these details.
Allocating new memory via setlength also clears the memory (+ the
overhead of allocating the memory).
