Re-entrancy of QtDBus Bindings

[Ogden, Nick]

Is anyone able to confirm that QDBusAbstractInterface::call() is re-entrant by the Qt definition of re-entrancy?

The documentation of the class does not explicitly say (with the exception of QDBusAbstractInterface::asyncCallWithArgumentList(), which is threadsafe) and the Qt documentation on thread safety / re-entrancy is a little unclear since:

"a class is said to be reentrant if its member functions can be called safely from multiple threads, as long as each thread uses a different instance of the class."

Which, if combined with the later stated:

"If a class is not marked as thread-safe or reentrant then a specific instance of that class should not be accessed from different threads."

Would seem to suggest that by default, if a class is not marked as thread safe or re-entrant it is implicitly re-entrant, but this sounds like a dangerous assumption to me.
