@jan-janssen You missed this line. It might not be called often but it is another redundant database query.

But this is dangerous. For example when you create a job object and remove the HDF5 file, then the loading of the job object with inspect() fails and returns an IOError still in the except case the job object is not available, so we cannot use job.id.
