I just tried it again and held down 'n' to visit all pages and the
memory stayed under 500 MB. I am using pdf-tools v0.90. I also just
tried with
https://file-examples.com/wp-content/uploads/2017/10/file-example_PDF_1MB.pdf
and the memory stayed under 400 MB. I'm somewhat confident that I
encountered memory issues in an Emacs instance without visiting a PDF
file.
