If typical code snippets like

(while (re-search-forward "..." nil t) ...)

copies the entire buffer for each re-search-forward call, then it's not
something that Emacs could use, I think.

But I wonder what the performance impact would be if functions like
`re-search-forward' just moved the gap somewhere (to before point, for
instance?).  Then the regex functions could just work directly on the
buffer, but without knowledge of the gap.
