Just as a clarification...

First, I am hoping that this only applies to a QWebPage that is being
displayed by a QWebView - a freestanding, mutex-protected QWebView could
be sent off to a thread without repercussions.  (In other words, the
issue is that the QWebView is trying to display the QWebPage at the same
time the thread is doing something to it.)
If that is true, I would also assume that applies only to *modification*
of the QWebPage - even if it is being displayed by a QWebView.  That is
to say, after the page has been loaded and thus is no longer being
changed, it would be safe to hand off a const reference to its QWebPage
to a thread.

Do I have this right?
