`save-selected-window` uses `select-window`.
[ Actually I meant to write `with-selected-window` which is even more
  directly related, but the same hold for `save-selected-window`.  ]

Because code within a `save-selected-window` may want to use `sit-for`,
`read-event`, `recursive-edit`, `read-from-minibuffer`, ..
