If the suggestion is that the QSql*Model in one thread should be 
connected to a QAbstractItemView in another thread, I'm afraid this is 
not good advice. The interface between model and view is not designed 
for asynchronous communication. Even if it seems to work at first, it's 
sure to end in grief.
