Just guessing, I'd say that static functions should be directly
callable, but to use a non-static member, you'd be required to pass
"this->Function" instead of "MyClass::Function". The reasoning is that
although you can't directly call a member function of a class, you might
be able to do so with an instantiated object. Thus "this". For
pthread_create() to not choke, it is also possible that you'll be
required to use static_cast<> on "MyClass::Function" during the create,
telling it to consider this a pointer to a function, not a pointer to a
class internally offset to a function.
