@Alexander: No.

To expand on what Konstantin said: QThread is NOT a thread; QThread is
a class that manages a thread.

Why is this distinction important? Well, it means that "QThread's
slot" = "The thread manager's slot" (NOT "The thread's slot"). If you
construct the QThread in the main thread, it will live in the main
thread. It doesn't live in the new thread. So when you make a queued
connection, the QThread's slot is invoked in the main thread, not the
new thread.
