However, the qjackctl connections window get actually refreshed, by querying and locking the jack graph instantaneously, only on these particular moments: 1. when a new jack client enters or exits the graph; 2. when any active jack client changes its own our others connections; this includes qjackctl normal but explicit user operation. 3. when the "Setup/Options/Auto refresh connections Patchbay, every (secs) ..." option is active. Although 1 and 2 are unavoidable, and as far as qjackctl is concerned it should be better addressed by a lock-free jackd implementation (as jackdmp promises), this later one (3) is not needed anymore and you better leave it off.
