The new version does seem to cut down on the evil pinwheel noticeably.
The CPU is still pretty heavily used when switching back and forth
between big files.  Should it not be possible to cache syntax
highlighting information, so that it doesn't have to be recomputed
every time one switches between unmodified files in a project?
