His context is very different from JIT font-lock since it's
not synchronous.  He basically sends the buffer to some external
processs which replies a minute(!) later with some highlighting
instructions.  Those instructions obviously refer to the buffer as it was
a minute ago.  Jit-lock works "between buffer updates", so it doesn't
have to deal with this problem.
