That's probably to make sure that moving the file is immediate/atomic.

This might still be an option, if you set "dateext" in logrotate (the
old files are then named mylogfile.YYYYMMDD*)

Then periodically run something like:
  cd /path/to/logs ; ls -1 mylog* | sort -r | sed '1,5d' | xargs echo rm
(This assume you want to preserve the 5 last log files)

Once you have tested it, you can replace "echo rm" with "rm" ;)

There are probably better ideas, but this quick hack should work.
