and maybe something that prevents multiple update requests piling up
while the window is being resized, unless the flag already takes care of

Ah, hm, ok, that's maybe 0.25 seconds for the man page of fvwm with 9441
lines.  It may not be a good test because the width does not change in
my case, and I have fast hardware.

Is there a reason for not to skip such an update when the length of the
lines did not change?

I didn't know you could update; this is like perfect because who prefers
dynamic updates can use those and who doesn't can use `u' if need be :)
