I thought that was expected behavior when you didn't declare factory virtual
in B, since the virtual jump table in A is overriding B's function table.
When I tried this, making B's factory virtual caused B's factory to get
called instead of A's.

I think you might need to call factory like "this->factory()"
the next 2 are from after the thread_group.create_thread() call. Once its in the thread it seems to revert to class A's methods.
Now, i know if i overload the threadcontroller class in B it'd solve all my problems, but the real threadcontroller method is alot more complex and class A has about 6 sub classes so replicating the threadcontroller in each of the classes would be a little tedious.
