  Log Message:
  -----------
  Deduplicate objects for iterative tasks

When iterative tasks encounter objects that already entered processing,
they skip them (with a SKIP outcome). This supersedes existing
deduplication methods in validity and trigger scanner tasks;
and is more reliable than was the latter one.

This resolves MID-6809.
