If you run `pause -wait-time 1h`, then (before that hour is passed) run another pause command, you would expect that the previous action postponed to +1h is canceled. This is not the case. Here is an example. ``` % curl --unix-socket /tmp/circologd-ctl.sock 'localhost/status' -s|jq . { "status": { "paused": false, "size": 20 } } % circologctl pause -wait-time '5s' paused % circologctl pause unpaused # wait some seconds... toggling again % curl --unix-socket /tmp/circologd-ctl.sock 'localhost/status' -s|jq . { "status": { "paused": true, "size": 20 } } ``` The error is that the `togglePause` goroutine is never canceled.
