At least on my system (backend and frontend on same system), it
seemed connected to mysqld.  Before I had seen any news about
the leap second issue, I stopped mythbackend, but mysqld still
consumed a steady 85% of a LCPU.  After stopping and restarting
mysqld, it immediately returned to using 85% of a LCPU.  After
several rounds of stopping and starting mysqld and mythbackend,
a reboot made everything happy.  Oh, and I didn't think to try
restarting ntpd with the date set command in between.

For reference, here are my relevant versions:

  distro/release: Mageia 1
  ntp:            ntp-4.2.6p3-2.mga1
  mysql:          mysql-5.5.23-1.1.mga1
  mythbackend:    mythtv-backend-0.24.1-20111019.0.1.mga1
