Just a wrapper for the barrier/semaphore thing we're doing constantly!
I only applied it in the importer rake tasks for now. There's other
call sites to move over to it, too!
I only now thought through that I can scrape these instead of enter
them manually, similar to how we did our Rainbow Pool scraper… hooray!
I'm actually writing tests for stuff too, wowie!
Just a bit more clarity of grouping! I'm also thinking about extracting
modeling APIs into a service file like this too, in which case I think
this would help clarify what it is.
