 I still don''t understand why this doesn't work.  It appears that the proc=
ess that launches the process doesn't get access to updated object attribut=
es.  When I set and check them in the object itself it behaves as expected.=
  When I check them from outside the object instance I get the initial valu=
es only.  Could someone explain what I'm missing?

When you fork into two processes, the child gets a copy of the
parent's state, but after that, changes happen completely
independently. You need to use actual multiprocessing features like
Queue and such to pass information from one process to another.
