load a large file (say, ..../emacs/src/keyboard.c) wait for jit-lock to
finish fontifying it in the background, then make a small change near the
beginning of this file, needlessly refontifying ~320kBytes consumes ~55%
of the CPU's power for 3½ minutes.
Why does a small change near the beginning refontify the whole file?
I suppose there are some small changes that might legitimately do so,
but I would not expect most small changes to do so. What's up?
I'm talking about the jit-lock that was
shipped with Emacs 21.1.
Can you please try the latest version? It is the only way to give
useful feedback.
