Maarten,
I understand that the messageReceived will never be called simultaneously
for the same session. But it can be called concurrently for different
IoSession's.
Let put a real example. A Server Application that received SQL Query from
different client connected to it.
Each client sent a SQL query to the Server. The Server has 10 connections
to the database.
How the messageReceived can process each client request (SQL Query)
simultaneously, using the 10 connections ?
