From https://github.com/politza/pdf-tools
It uses poppler to render PDFs. "...there is one feature (following
links of a PDF document by plain keystrokes) which requires
imagemagick’s convert utility."
When I woke this morning, memory usage went from about 200-300 MB to
about 3 GB overnight. No PDFs were open.
