In the great tradition of answering your own question. I just tried the identical process in LC7
Loading the text file takes memory up to a similar size as in LC 8.1.10, but the script runs successfully and even repeats for multiple collections of keywords without memory pressure rising at all, and LC memory never rises above 300MB Everything seems brisker, too.
