Lock contention during inserts

During mass inserts, we have some locking contention in tables referenced by
foreign keys. It�s a 8.0.3 box
and I know that 8.1 solved this but I would like to know if there is an easy
and safe way to only apply this patch to 8.0.3?

If it were a simple fix it would have been fixed many versions ago.
Update to 8.1.
