My test battery is stuck

This addresses a problem hit by @matthewrmshin in his new job-status branch: 
 > I cannot get the test battery to work. Each time I run the test battery, a random suite or two will get stuck. It will give the following log output (snipped) after the 1st task, until it times out.
