When a solution evaluation on backend is finished, results are saved to

steps needs to be done before the results can be presented to users. For

However, concept of asynchronous jobs is then introduced. This type of job is
useful for batch submitting of jobs, for example rerunning jobs which failed on
worker hardware issue. These jobs are typically submitted by different user than

this case it is more reasonable to load the results immediately and optionally
send them with the notification. Exactly this is also done, special asynchronous
jobs are loaded immediately with email notification to the original job author.
From a short time distance it seems that immediate loading of all jobs could
simplify loading code and has no major drawbacks. In the next version of ReCodEx
we will rethink this decission.
