Small API Tweak to Task (Worker)

[Sven Reimers]

What I probably was thinking about is task that written with the intention
that they should not be cancelled, e.g. calculations you want a result of.
It is not so much about you could not make them cancelable, but to show
this is not intended to be cancelled...

Hope I could clarify my train thought.

Thanks for listening
