---------------------------------

good that it works
fyi: for inspiration on a unit test; have a look at: http://svn.apache.org/viewvc/activemq/trunk/activemq-core/src/test/java/org/apache/activemq/usecases/ThreeBrokerQueueNetworkTest.java?view=co

> I would like to add a schema. I hope I will be able to add it later. I don't see it
> I have 3 processes with one embedded broker (BSV, client, server) in the same network of brokers (non duplex but bi-directionnal).
> I have a fourth standalone broker
> My "client" and my "server" process are connected a second time with a "manual" tcp connection to the BSV process.
> My "client" and my "server" process are connected a third time with a "manual" tcp connection on the standalone broker.
> In this case, if my process BSV is stopped by an interrupt (CTRL-C) (which closes the embedded connection, and the embedded broker), and if simultaneously, I want to stop gracefully my "client" process (close all session, close all "manual" connection, stop embedded broker), one session thread stays up and never terminates

> It is a session associated with the BSV link (I don't know if it is a session associated with the network of broker, or a session associated with my manual connection)
> A CTRL-C on the process terminates the process
> It doesn't happen if stop are not simultaneously done.
