> When writing to an index beyond the last index written to, Variable Length 
> vectors set the 'empties' by writing a zero length byte array to the indexes 
> that were skipped.
> This is, as it turns out, sometimes an expensive operation, and is completely 
> unnecessary as all that needs to be done is to set the offset vector 
> correctly.
