This is a sampling of some of the faces and their counts. It's only
about 300 of the 1300, I'm having tmux copy/paste trouble:

  41 default
   6 font-lock-builtin-face
   4 font-lock-comment-delimiter-face
   7 font-lock-comment-face
   1 font-lock-function-name-face
   6 font-lock-preprocessor-face
  12 font-lock-string-face
   1 font-lock-variable-name-face
   1 header-line
  41 line-number
  20 line-number-current-line
  48 nano-face-faded
  21 nano-face-header-ancillary
  13 nano-face-header-default
   5 nano-face-header-faded
  12 nano-face-header-strong
  12 nano-face-popout
   6 nano-face-salient
  14 nano-face-strong
  41 shadow



When emacs is idle, it seems to spam face lookups continuously. Here's
a sample of that:

  48 default
   5 font-lock-builtin-face
   6 font-lock-comment-delimiter-face
  10 font-lock-comment-face
   1 font-lock-constant-face
   3 font-lock-function-name-face
   1 font-lock-negation-char-face
   5 font-lock-preprocessor-face
   5 font-lock-string-face
   3 font-lock-variable-name-face
   1 header-line
  48 line-number
  24 line-number-current-line
  59 nano-face-faded
  21 nano-face-header-ancillary
  13 nano-face-header-default
   5 nano-face-header-faded
  12 nano-face-header-strong
   5 nano-face-popout
   6 nano-face-salient
  18 nano-face-strong
  48 shadow
