I would not find is a good approach, if exceptions were silently
suppressed.

If we know that during deletions exceptional cases could happen,
we should inform the component lookup process that we are doing
deletions such that it can be less strict in its behaviour.

However, usually the "I am going to be deleted" event is
signalled before the actual deletion takes place. Therefore, the
event processing still should find all utilities around.
