I think the doc string for redisplay-preemption-period is the best 
source (look in dispnew.c sources for it).

I don't remember, but from the look of it, it seems related to running 
text-only emacs over very slow lines (2400 bps and up), and trying to 
make a less drastic version of redisplay-dont-pause, so that the screen 
is updated at least sometimes and to some extend even if input arrives 
at a steady rate without pause.

I'm not sure this is relevant anymore.
