QSslSocket: stabilize triggering for write
QSslSocket::writeData() accumulates outgoing data. It might be called
multiple times during the event processing (most likely from the long
loops which serialize the data).
As this function produces a notification event on each call, it's
possible to get a huge number of slot invocations on the next event
loop run, when we are interested in a single flush.
So, this patch protects the code against uncontrolled signal emission
that results in the lesser resource usage.
