qtdemo does not show example docs in assistant

Description
If you start qtdemo, select an example and press the Documentation button at the bottom, the assistant application starts but it will not navigate to the requested page and will show the previous page (if you visited any) or the home page (otherwise).
Running qtdemo.exe -verbose shows that the URL sent by it to assistant is correct (doing assistant.exe -showUrl <url> from the command line works perfectly).
qtdemo talks to assistant through the QProcess communication channel AFAIR. This may be a regression of our latest QProcess changes.

I have fixed a r701 regression in r1045 (related to reading remote assistant commands from the pipe) but there is still a problem of high CPU load and unresponsiveness of assistant when started in -enableRemoteControl mode which actually prevents it from working right.
Somehow it is related to some documentation cache creation.

Fixed in r1046. The Assistant code is quite complex so it was really hard to find.
Starting assistant.exe with the -enableRemoteControl shows the same annoying system freeze (100% CPU load) as starting it from qtdemo. Starting it w/o this switch doesn't show this behavior.
