    Description

      QCalendar class uses its internal containers shared across the class, such as Registry::byId and Registry::byName. But the access to those containers is not protected from multi-thread access.  As a result, despite the document's "all functions in this class are reentrant" statement, this class can be used safely only form one thread.
