Dear emacs maintainers,

I run emacs on a remote Debian-testing server on X over SSH
from my local Mac OS X machine.  

I compared these two cases:

remote$ /usr/bin/emacs24 -q --eval '(+ 2 3)'
remote$ /usr/bin/emacs24 -q --eval '(setq select-active-regions nil)'

In the former case, once you press C-Spc (control-space), the emacs
text cursor moves only very slowly.  In the latter case, the text
cursor moves normally.  I repeated the two cases alternately for five
times or so and always got the same contrast.

My local X11 server is XQuartz 2.7.5 (xorg-server 1.14.4).
My local machine runs Mac OS X 10.6.8.

When I'm on my Debian server and invoke emacs24 locally,
I don't notice any slowness in cursor movement.

By the way, I used '(+ 2 3)' only because I wanted to go to the same
*scratch* buffer to select the same text and I don't know a no-op
function in Lisp.

Regards,

Ryo
