Ahh, that would explain why my examples replaced
smtplib.stderr while others replaced sys.stdout.  I'm
working out of a CVS build.

In a cursory look of your code I though you were implementing
a sort of thread local storage.  Looking at it again I don't
see how

         thread = threading.currentThread().getName()
         try:
             self.lock.acquire()
             if thread in self.ios:
                 self.ios[thread].write(data)
             else:
                 t = self.ios[thread] = StringIO()
                 t.write(data)
         finally:
             self.lock.release()

isn't using thread local storage in
    self.ios[threading.currentThread().getName()]

Agreed with the rest, though while I've used Twisted
some and think I understand the idea of a reactor
based system I still haven't internalized it yet.
