(while main thread was harmlessly blocking on vcl::SolarMutexObject::acquire
during Application::Yield).
SwAccessibleParagraph -> SwAccessibleContext is a UNO object with a
SwAccessibleMap * pMap member. However, lifetime of that SwAccessibleMap
appears to be controlled by SwViewImp (pAccMap member, created in
SwViewImp::CreateAccessibleMap, destroyed in ~SwViewImp) while lifetime of
SwViewImp appears to be unrelated to lifetime of SwAccessibleParagraph UNO
object.
