So here's a patch to do that. Writing the bulk commit function was a fun exercise, and I found a couple other places to apply it, too, shaving off ~7.5 seconds from my test runs. Not ground-breaking, but I think it's nice to have a solution where we don't have to be afraid to generate a bunch of commits.

I'm sure there are other spots that could be converted, too (either ones that are slow loops now, or ones that use fast-import themselves but could be made more readable by using the helper), but I stopped digging after finding the low-hanging fruit here.
