Motivation: We temporarily store channel creation requests in NIOSSHHandler before passing them to the multiplexer while we wait for the handshake to complete. This is fine, but if for any reason we get removed from the pipeline while we're still holding some, they must all be cancelled. Modifications: - Correctly cancel creation requests on handlerRemoved. - Verify behaviour in tests. Result: Fewer hangs on channel creation.
