The ImplSVEvent goes into the various platform event queues. When all
goes well it eventually gets dispatched back into the platform
independent code and ends up in ImplHandleUserEvent where it gets
The SalGenericDisplay will delete ImplSVEvents which *didn't* get
dispatched in SalGenericDisplay::deregisterFrame.
So presumably your leak doesn't hit either getting dispatched and thus
deleted, or detected during some teardown case as an undispatched event
and deleted by the platform-dependent event queue handler.
