[omniORB] A question about ORB thread model

[biguo]

    Hello,folks! I have a question about ORB thread model.In CORBA
model,there is a thread scheduling in handling client request and a
client request correspond to a server thread . I think,it should be a
user level thread.According to my understanding,  for each client
connection,only a thread are automatically allocated on the server to a
client connection.A ORB implementation only can generate one OS(such as
Unix or Windows ) task.Is it right?Thanks.
