For a good measure, also disable global-eldoc-mode.  I've found long
ago that blink-cursor-mode and global-eldoc-mode get in the way of
debugging and testing various redisplay problems, because they tend to
trigger extra redisplay cycles.

For an even cleaner environment, I suggest to disable all the timers
that we run by default (see "M-x list-timers").  Timers change how our
main loop behaves, and the routine redisplay calls are part of the
main loop.
