I'm working with Bloomberg and the tick42blp bridge, and I have an application which starts multiple clients, each one in a different thread, and each one can be subscribed to different subjects. I had a problem, when the second client started, it failed because the transport with that name (blp_tport) had been already created when the first client started. Then I decided to make the transport static so all clients can use the same instance, but I am not able to destroy the transport until the last client is closed, otherwise, clients that are using the transport will fail.
