A CLI command "wait" was added in [0], and a related function vlib_process_suspend was there in the first open commit [1]. I guess both are intended to be used during initialization, forcing an exec script to slow down, e.g. for a DHCP response to arrive.
But when I tried (in [2]) to teach "wait" it does not need to stop workers, the verify job run [3] showed no effect. If I am looking correctly, that is because each worker gets only a shallow copy [4] of the process list. Is this behavior intended? Is there a way to pause only CLI processing without also affecting worker threads? Vratko.
