More thinking on this question. It is a scheduling issue. There are the
process, the schedule capability, and the schedule which implements the
scheduling contract.
The schedule should obey what is defined in the schedule capability. If
the schedule capability has the option to reveal restarts, the process
should be allowed to react to restarts.
Note that no conclusions are drawn at the moment.
