Hi Andrea!

Thank you for implementing this blacklist; it turns out that
char-fold.el was the only file my laptop could not handle[1], though as
you'll see org.el was a strong contender.

It took 3 days, but make -j1 successfully ran to completion on commit
92cf4bb.  In comparison, I've just compiled commit 9d8fc3a on master
from scratch, and it took exactly 1 hour 35 minutes.

As soon as I've figured out how to use the elisp-benchmarks package,
I'll post some figures; is there a specific place (bug number,
emacs-devel thread) where you usually collect such feedback?

I've attached some more graphs on the compilation process, as well as
the source material[2] (measurement script, measurements, and plotting
script).

The overall picture (only files which took more than 10 minutes to
compile are labeled):
