Now I'm seeing the use case where each trivial cursor movement causes
~100 calls to bidi_shelve_cache, and each call copies ~1.5M of data.
If there is a redisplay problem which makes this unavoidable without
rewriting 1/2 of xdisp.c, then "broken by design" is the only thing
I can say about all of that mess.
