Thanks Walter. Wow, so I'm thinking should be good to go then. I've already
uninstalled rsyslog, which could contribute to excessive writes, and the lock
file my project creates I have dropping onto a ramfs volume. So hopefully any
writes are now at a minimum. In the main function of my script I'm also
issuing a sync && sync, so hopefully that helps too.
