Any way to re-use the Channel..

[Trustin Lee (이희승)]

Hi Wesly,

Unfortunately, there's no way to reuse a closed socket channel at this
moment.  You need to create a new socket channel once an existing
socket channel is closed.

There's a to-do item related with this though:

  * https://jira.jboss.org/jira/browse/NETTY-70

An idea to improve the feature request I've written would be appreciated.

Thanks,
Trustin
