I don't think Philippe is talking about those kinds of situations (that 
cause Fox to call exit()), but rather situations where ruby callback 
raises a ruby exception, and it propagates outside of the #run call.

Is there any reason why the following code won't work?

   rescue => ex
     if ... # ex can be retried
