Ok.

wisi supports partial parse; if a buffer is larger than a user-settable
threshold, for font-lock it parses only the request region of the file,
expanded to reasonable start/end points.
So in that mode, the initial parse of even a very large buffer is fast.
However, using that for indentation is problematic, which is why I'm
implementing incremental parse.
I think continuing to support both will be useful.

It should only freeze write operations on that buffer, so marking it
read-only while waiting for the parse results might be best.
