Thanks.  Could you include in a comment a precise description of the
inf-loop?  Reading the new code along with the above commit message I'm
left wondering exactly what was the problem: was a single redisplay
inf-looping (if so, where?), or was one redisplay immediately
causing another redisplay (if so, why do the subsequent redisplays
still set the selected frame's redisplay flag)?
