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.
