the memory barriers of QComObject can be slightly relaxed, which should
improve performance of the reference counting:
* AddRef does not require any memory barriers, we only need to increment
the reference count.
* Release has a "release" semantics, unless the reference count drops to
zero. In this case we need to acquire to ensure that writes from other
threads are visible.
