Revert to older batch size logic to keep memory usage down during
execution phase and closer to the --batchSize flag size.
Spotted a "leak" in key generation as well. The unsafe pointer keeps the
byte slice around for as long as the batch is not committed, takes up a
fair chunk of memory surprisingly doing that so removed the unsafe
pointer usage giving the GC some chance to clean up along the way.
Moved the batch rollback into a defer func call rather than allowing
them to stack in the for loop. If this isn't going to work just let me
know and can change it back.
