wall of text pumping out while in shell

wall of text pumping out while in shell

[Le Wang]

Hi all,

I'm trying to use my shell within Emacs more regularly.  One problem
that crops up often is a long running command unexpectedly is
outputing a tremendous amount of text (often having very long lines).
Now Emacs' display engine is the bottleneck to the program finishing.
I don't want to prematurely kill the program.

How do you guys solve this?  Is there a way to say I temporarily don't
care about getting live updates from this shell, and resume later?

Don't display the buffer.

Turn off the comint-scroll-to-bottom-on-output option. Then type C-p 
when the output starts. The output will go to the buffer, but it will be 
off-screen so the display engine doesn't have to render it. The only 
thing that updates is the scroll bar, because the relative position of 
the window in the buffer is changing, and the mode line's percentage.

You can also switch to another buffer.
