I guess what I was meant to say way  "QtWebKit actively encourages that
application have only 1 QNetworkAccessManager, 1 CookieJar and 1 cache that is
shared among all of the existing QWebPages."

You can have multiple QNetworkAccessManagers and they could share the objects,
but it is not encouraged.  For example when you set a cookie jar on a
QNetworkAccessManagers it sets the parent to itself.  So it is technically
possible the network code is not designed to work with this without some extra
work.
