QLocalSocket::abort() does not abort but wait for data to be sent

QTBUG-14939 seems to describe the exact same problem. The linked source changes in conjunction with labeling it fixed for 4.8 is seems invalid though, as I can still see the problem in 4.8.

QLocalSocket::abort() is supposed to “immediately close”
http://qt-project.org/doc/qt-4.8/qlocalsocket.html#abort

QLocalSocket::abort() calls close()

close() calls disconnectFromServer

I have a client to a server. If server queued data for the client which he did not read for x time, the client is considered dead. Hence, the server wants to abort. My issue now is that abort() actually seems to wait for data delivery; 30 s.
Specifically, in my use-case bytesToWrite() is > 0
, thus going into `disconnectFromServer()`.
