No, I think I haven't explained it well enough.  You will not lose
a character until waitforinput() gives up and leaves the loop
entirely. It is still possible to loop as many times as you like
before giving up.   Total wait time = time per loop X # of iterations.
If you still have no response from the X server after several
seconds, I think losing a character is the smaller part of your
problem at that point.

If things are functioning properly, then a loop like the one in
animate.dem will only go through the waitforinput() loop once
per replot even if there is unexpected terminal input. So making
the per-loop delay shorter should take care of the problem.
