Sure. That's msync::ddacq. Works just fine as long as all dtor's 
accesses are data-dependent (with respect to object address) or when
all it's "(*this)-independent" accesses are reads of immutable data. 
If not, then msync::ccacq with control dependency is the best match. 
Otherwise (when msync::ddacq is insufficient and you have no control 
dependency for msync::ccacq), straight msync::acq is mandatory.
