Well, it does more than control the delay -- it also allows switching
the echoing off, so I think the name's OK.

Yes, it sets up a delay, and if your redisplay is too fast, the clearing
and re-drawing will be noticeable.  (I can't reproduce it on Debian.)

No, the delay is because many people find echoing the unfinished
keystroke to be disturbing.

So I think everything here basically works as designed, and I'm closing
this bug report.
