I am having issues with some images that report 'ready' slightly before they are actually ready to do real business. One in particular would need just another few seconds to finish its infinispan-syncronisation (i.e., it is ready to sync, but not with the sync).

My proposal would be to define a switch like -g | --graceperiod SECONDS with default 0 and insert a suitable wait als else branch of this if [ "$SUCCESS" != "$SCALE" ]; then.

I can create a PR if that is desired.

Best regards
