connections waiting on condition before sending the response

[Benoit Perroud]

Hi all,

I'm really new in Netty, and I don't know where to begin to achieve the 
following behavior :

I have connections that should wait on a condition before sending the 
response. For example "Hang all the client till a particular request is 
done".

I tried to put the Channel in a ChannelGroup in messageReceived, and 
then to have a Runnable waiting on the condition and iterating on the 
ChannelGroup when the condition is met.

I also try to add a threadPool in the pipeline before my handler, but my 
tires do not accept more than 2 connections, the other hang on.

Thanks in advance,

Kind regards,

Benoit.
