<pre>OK, by increasing the terminal size, I do indeed see that the visual bell is
really rather slow. During that time, X is using up 100% CPU, so it's probably
something highly unoptimal happening in the DDX.
It seems like almost all of that CPU time is going into fbSolid() from libfb,
but sadly perf isn't telling me where it's getting called from for some reason.
I'll try to look into it later, but wanted to record this observation in case I
don't get to it.</pre>
