Please describe the problem:
Gnome-Terminal generates high CPU usage when there is a lot of output.

I have a 2.16ghz Intel Dual core. There is a process running in a
gnome-terminal which itself does not take much CPU usage but generates a lot of
output (perhaps 100 lines / second). In such case, Xorg-Server has very high
CPU usage: between >50% on both CPUs if Gnome-Terminal is in the foreground or
~30% on both CPUs if it is in the background.

Could it be that on every change in the output, Gnome-Terminal sends the
*whole* data (everything in the textbox) to Xorg? That would explain the high
CPU usage.

On older systems (that bug occurs for me on all my systems), such a case is
almost like a DoS-attack, the mouse is almost not moveable anymore.


Steps to reproduce:
1. Start Gnome-Terminal.
2. Start any application which generates a lot of output.



Actual results:
CPU usage rises high.

Expected results:
No change, a stable system.

Does this happen every time?
Yes.
