Hi,

The enclosed changeset fixes all bugs/inconsistencies concerning process
termination listed below. It's a simplified version of the previous
proposal. Feedback very welcome indeed!

The idea is to simply extend the existing mechanism for completing
halfway-through unwind blocks and let it deal with *all* unwind blocks.

best,
