Fix #2783: detect black-hole loops properly
At some point we regressed on detecting simple black-hole loops. This
happened due to the introduction of duplicate-work detection for
parallelism: a black-hole loop looks very much like duplicate work,
except it's duplicate work being performed by the very same thread.
So we have to detect and handle this case.
