By default they do.  They can also share a scheduler, so you can have an 
active object consisting of a bunch of active_functions all sharing one 
scheduler.  That gives some automatic thread safety since all the user code 
run by the active_functions sharing the scheduler is run in the same thread.  
If each active_function corresponds to a method on an underlying ordinary 
object, then methods of the underlying object can all access and modify the 
object's internal data without worrying about concurrent access, since they 
will all be running in the same thread.
