Thread-safety documentation

No member functions of QThread class is documented as thread-safe. If it is truly the case, then it means that all member functions must be called from the thread in which the QThread instance lives, not the thread which the QThread manages. As a consequence, the object returned by QThread::currentThread() should never be dereferenced directly, and the example given for QThread::isInterruptionRequested contradicts this.

Also, QObject::deleteLater and QObject::thread() are not documented as thread-safe.
