Hmm... I was thinking we could expose `inhibit_buffer_hooks` as a Lisp
variable (so we can set it without having to match names, which I find
ugly and brittle), but we'd want to `setq` it rather than let-bind it.
But while it's easy to set it before running kill-buffer, we can't set
it before calling generate-new-buffer :-(

How 'bout adding an optional argument to `generate-new-buffer` to set
`inhibit_buffer_hooks`?
