No. My step #3 makes the QTcpSocket live in the service thread as it is
created as an automatic variable of the ::run function which is
*in the thread*. Don't be confused by the int file descriptor which starts
in the main thread and is passed down to the service thread. Integer file
descriptors are process-global. The main thread hands the fd off to the
service thread and never touches it again.
