In a blocking application, receiving the results of write operations
must be synchronized with the waitFor...() functions. But, clearing
the buffer in another thread can cause the code
localsocket.write(...);
QVERIFY(localsocket.bytesToWrite() > 0);
to fail unexpectedly, if the socket has been disconnected between
the calls.
So, defer resetting the buffer until checkForWrite() is called.
