Oh, please. This is not too hard to code.

My mind rolling around following choice(s)  (there may be others i don't see).
What would be a proper way to handle error during #finalize.

[ executor finalize ] on: Error do: [:ex |
  self handleFinalizationError: ex  "where self is registry"
 ].

or:

[ executor finalize ] on: Error do: [:ex |
  executor handleFinalizationError: ex
 ].


of course, i should catch this error in test, so i can verify that:

a) test is get notified upon synthetically made error
b) no matter what i do inside error handler (up to 'Processor
activeProcess terminate'), a finalization process continues working
(or restarts without losing remainder of executors).


Also, i used #ensure: and #ifCurtailed: but i tend to forget where
they are applicable and how.
So, little help in this regard will be wellcome.
