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".

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
is slow with my test case. The datestamps here are from a machine in
the US/Pacific time zone.
