Anything that can generate 6kB lines in your complation buffer should
do.  Try calling a shell script that writes the long line.  For me, it
was a long compilation line from "make".

Indeed! The attached script 'prints' 6x1024 'x' characters, and on
GNU/LINUX KUBUNTU 8.04.02 it takes:

4 seconds with Emacs CVS LESS THAN OR EQUAL TO (<=) 20090129 15:30

2:15 minutes, i.e. 60x2+15=135 seconds with Emacs GREATER THAN OR EQUAL
TO (>=) 20090129 15:40!

To reproduce:

$ emacs -Q &

M-x compile
C-a C-k

I was also able to narrow it down to around that date.

  cvs up -D 2009-01-29

works fine with my test case,

  cvs up -D 2009-01-30

see above...
