I temporarily added

  (advice-add 'call-process :before #'debug)
  (advice-add 'start-process :before #'debug)

to my ~/.emacs and restarted, and there are several packages which
invoke external commands at startup, e.g., Magit trying to figure out
the defaults I've set in my ~/.gitconfig.  So that seems to be expected.
