This is a well-known phenomenon. Perhaps you are using your machine
at the time prelink runs, whereas before you did not. IMO, prelink
performs a non useful task, anyway. Don't kill it in midstride,
however. You should be able to find it in cron and make it stop

# ls -l /etc/cron.daily/prelink
-rwxr-xr-x  1 root root 1603 May  5  2004 /etc/cron.daily/prelink

Oppose globalization and One World Governments like the UN.
