that would be easy if we require that prior to wrapping only setters can
be used and setters must have no internal side effects. of course, that
means that opening the device in a class-specific way needs to be done
in the thread already. doing *that* generically may turn out, uhm,
challenging. it may be more appropriate to have a QFooWaiter for every
relevant QFoo.
