QEventDispatcherWin32::registerTimer: Failed to create a timer

When waitingForFinished( ) is executed continuously with QRemoteObject, the error like this occurs.

QEventDispatcherWin32::registerTimer: Failed to create a timer (The current process has used all of its system allowance of handles for Window Manager objects.)

The reason of this is because of the following code in qremoteobjectreplica.cpp

QConnectedReplicaImplementation::waitForFinished(...) {
....
QTimer::singleShot(timeout, &loop;, SLOT(quit()));
..
}

Every time when waitForFinished () is executed, QTimer :: singleShot () is executed with 30000ms. QTimer :: singleShot () accumulates every time it is called because there is no way to stop the timer. If you execute waitForFinished () about 1000 times within 30000ms, the timer will run out and it will not work.

One solution would be to correct qremoteobjectreplica.cpp as below so that the timers that are no longer needed are discarded.

QTimer t;
t.setSingleShot (true);
connect (& t, & QTimer; :: timeout, & loop ;, & QEventLoop; :: quit);
t.start (timeout);
