weird. in the past couple of weeks, #foldingathome #fahclient has now hit two different of my home machines with a corrupted work unit that causes it to try to start, fail out as "INTERRUPTED" and sit idle "waiting for fahrun". Restart doesn't clear it. If I ignored it, it'd sit idle until the work unit expired, but deleting the contents of the config/work directory and forcing it to pull a new WU fixes it.
