Review Comment:
I didn't want to make the events listener be responsible for interpretation
of the exception. This is cross-project API and the way how we learn about
preemption or timeout may change over the time - for example, it may not be an
exception at all, or we may move the reporting to the place where the exception
is not thrown yet...
