> It would be handy to be able to fail with a nice message during init, such as 
> 'database not available' or 'no config file found' or whatever.
> At the moment, if you try that during init, you get an IllegalStateException. 
>  I've attached a patch which removes this restriction in DaemonLoader, but 
> failing at this stage doesn't stop the c code from calling start.  I could 
> work around this in the DaemonLoader, but not sure that is the right 
> approach.  I'll have a go at doing a patch for the c-code, but I'm not a 
> confident in my c skills...
