What happens to the thread affinity of a QObject created within a worker thread which then terminates?

Let's say I call QtConcurrent::run() which runs a function in a worker thread, and in that function I dynamically allocate several QObjects (for later use). Since they were created in the worker thread, their thread affinity should be that of the worker thread. However, once the worker thread terminates, the QObject thread affinity should no longer be valid.

The question: Does Qt automatically move the QObjects into the parent thread, or are we responsible in moving them to a valid thread before the worker thread terminates?
