I ended up running my 2nd file first and my 1st file second. The 2nd file waited for a 'finished' file write that the 1st file did once it, obviously, finished.

At this point, it seems like the database would be a better place to store messages for files to be able to pass between each other, but a file would also work for a quick and dirty job.
