Unzipping layout-test-results might take a long time (few minutes), especially with a S3 mount for results. e.g.: 8 minutes in https://build.webkit-dev.org/#/builders/28/builds/5 However, while unzipping is done on server, we don't really need to block the build during that time, we can move the unzip operation to background so that the bot can process the next build.
