Review Comment:
> Not sure if its a good idea or not but could do something like this to
kick off the bulk imports in parallel.
Its an interesting idea. Running the imports serially vs in parallel each
have the opportunity to expose different bugs. Going to experiment with doing
both in two test to see what that looks like for code sharing.
