Travis: Initiating build for commit '20a6b713d119eebcb7b4c752232b023ceac0cdb2' on branch 'master': Fixes #5842, use -x option when invoking ps in asynchronous process execution code so processes that aren't attached to the terminal will be returned. Not using it causes climulti:request commands to fail when being executed by cron on some systems. The command will return early w/ no data.
