(Bug to note ideas discussed during the bug review call)

In its current form, the reproducibility build (using diffoscope) has no limit in memory usage. When testing meta-oe reproducibility, its high memory usage can trigger OOM kills on AB.

In first-to-last to try:
* this option:
--max-diff-block-lines-saved LINES
    Maximum number of lines saved per diff block. Most users should not need this, unless
    you run out of memory. This truncates diff(1) output before emitting it in a report, 
    and affects all types of output, including --text and --json. (0 to disable, default: 0)
* most likely need to be coupled with 
--max-diff-block-lines LINES
    Maximum number of lines output per unified-diff block, across all pages. 
    (0 to disable, default: 1024)
  ... to avoid generating no empty output
* Re-explore '--no-default-limits' option (see call[0]) => look at git history on why it was added.
* If limiting memory from diffoscope is not possible, use an external tool:
  * prlimit? (https://man7.org/linux/man-pages/man1/prlimit.1.html)
  * (during the call, I mentioned a "timeout" tools but it was not the GNU Coreutils tool, but this one https://github.com/pshved/timeout)
  * cgroups? (feasibility on AB is uncertain)
