Out of curiosity, how long does pytype take to run in a clean source directory, without any state files?
  
  It takes 15-20 minutes on a 2018 Mac mini.  In addition to the disabled files here, I've disabled:
  
    mercurial/httppeer.py
    mercurial/repoview.py
    mercurial/localrepo.py
    mercurial/revlog.py
    mercurial/merge.py
    mercurial/testing/storage.py
  
  But I've also added back these, and sprinkled various disable comments around:
  
    mercurial/bundlerepo.py
    mercurial/error.py
    mercurial/exchange.py
    mercurial/policy.py
    mercurial/pycompat.py
    mercurial/scmwindows.py
    mercurial/windows.py
    mercurial/wireprotoframing.py
  
  Even with the state files, it seems to take 10-15 minutes or so.
