     Only if the context of the run() function is the same as that of the SomeThreadImplementation instance at the time the run() method is invoked.

     You can't define away the differences between OO and other techniques that easily.

     It does not, however, enable the type of analysis the orignal poster was suggesting might be possible. Because of the OO focus on behavior, data-only analysis is not able to provide a full view of an OO system.
