> There are a few places where scanner threads are interrupted with 
> .interrupt() instead of .interruptIfAlive(). This means that if they're in 
> the midst of the checkFileSystem operation, it'll end up catching the 
> interruption there, determine that the filesystem is down, and shut down the 
> whole server. Other nasties can also result.
