A similar thing I've seen done on occaision is to have a cron job come
in and move the file to another point on the same disk. 

As you've got a filehandle open for that file and you're staying on the
same disk it doesn't (or at least shouldn't) effect files being written.

Of course, this also comes under the title of "cheap hack"...
