Here's the consultant who wants to make his plane
home answer...set up another cron job that runs 1
minute before the logrotate cron job and does a
  sleep 50 && sync 
so you only have a few seconds of dirty buffers
to sync from the real cron job.

What does
  /proc/sys/vm/dirty_writeback_centisecs
say?  You might be able to get a faster sync time by
making it smaller.
