Could you set it as a configurable property or use the same defined here?

Thanks for input :)
added support for -DChannelManager.timeout=123456
Notice that its using a new property and not reusing -DAuthenticationManager.timeout
I felt that it would be strange to use a property named after another class.

Nice, thanks :)
When can we expect a official release?
I would like to avoid depending on a internally released Trilead.
