How are you going to "switch to that buffer" ?
Can you really expect that none of the callers have done some
kind of save-current-buffer ?

Hmm...looking at the code, it does seem like there really isn't
any save-current-buffer interfering.  Can we rely on that ?
Should we document it ?
It's rather unusual for a major-mode function to switch the
current buffer.
