search.c:
#define REGEXP_CACHE_SIZE 20
I don't know but doesn't font-lock alone sometimes need more
than 20 regexps?
Maybe it does, and maybe we should increase the cache size;
but why would this make isearch slow?
Is the slowness due to fontification when isearch shows
new parts of the buffer? If so, repeating the same isearch
will be fast. Is that the case?
