You're correct in that currently jobs will be set to error and need to be 
automatically rerun by the Galaxy user.  There isn't anything in place for 
automatic retry after spot instance failure, but this is definitely something 
we plan to implement in the near term - a generalized retry and resume 
mechanism will be useful for both cloud and local instances.
