[Qt-interest] Major bug in QAbstractSocket's methodwaitForReadyRead()

[Patric]

Thank you for answer, Srdjan,
the problem here is that the method don't wait for the timeout, which makes 
it unsusable. But it's a mistery why somethimes it works, somethimes not.
Anyway, I have found workaround for this situation. But it's very helpful 
method.

Best regards,
Patric
