Don't rewrite.  Wrap.

def frameworkify_threadprocedure(threadprocedure):
    def wrapped_threadprocedure(*args, **kwargs):
        threadprocedure(*args, **kwargs)
        post_thread_ended_notification()
   return wrapped_threadprocedure

Now instead of 
   thread.start_new_thread(spam,...)
use 
   thread.start_new_thread(frameworkify_threadprocedure(spam), ...)

Write all the logic for collaboration with the main thread just once
in wrapped_threadprocedure, and you can keep the individual thread
procedures simple and framework agnostic.

HTH, Anders
