The flag in the C structure has the advantage that it can be easily
set and reset from C without the need to temporarily bind Lisp
variables, which then involves unwind-protect forms etc., and as a
side effect makes the entire operation slower.  Also, a flag can be
set/reset regardless of whether the buffer already finished being
created, whereas buffer-local variables must have a live buffer.
