Hi Heiner,
well, when shared only within _one_ UTF2 thread-unsafe environment,
you don't need to explicitely make them atomic. But see below...
It is also the question whether calls to acquire and release across
thread-safe/-unsafe boundaries should be guarded (like normal UNO method
calls) or direct. For acquire, the combination of atomic acquire (how
it is typically implemented by C++ UNO objects) and direct call would
probably be fastest. For release, the problem is that many C++ UNO
object implementations do nontrivial work in their destructors (which
often is a bad thing, bad that is another story), so that release should
better be guarded.
