how to write to channels periodically

[Norman Maurer]

Hi there,

using a ChannelGroup sounds like the right solution here. Just a minor
thing.....

You don't need to remove the Channel from the ChannelGroup by yourself
if you use DefaultChannelGroup as it does this already for you via a
ChannelListener.

See:
http://docs.jboss.org/netty/3.2/xref/org/jboss/netty/channel/group/DefaultChannelGroup.html

Bye,
Norman
