Here is implementation of WTimer::singleShot():
template
void WTimer::singleShot(int msec, const F& f)
{
WTimer *timer = new WTimer();
timer->setSingleShot(true);
timer->setInterval(msec);
timer->setSelfDestruct();
timer->start();
timer->timeout().connect(f);
}

timer deletes itself in "shot".
But it leaks if it never shots.
This can happen for the following reasons:

• session deads before it shots,
• memory leak attack.
