Stop button is displayed even after retease is complete

Issue Summary

I have very few nodes on my test site. I run re-tease, and it completes very quickly. However, to do another retease, I have to click the Stop button, even though it says the first retease already completed. This isn't a huge issue in the sense that everything is working, but it's a bit confusing and it forces me to click around needlessly to do another retease.
