Kristian Rosenvold commented on SUREFIRE-707:
---------------------------------------------
Also here I suspect forkedProcessTimeoutInSeconds set to something non-zero
when this happens ?
Those runaway threads seem to indicate forkedProcessTimeoutInSeconds is not
safe to use in parallel mode at the moment. Although the issue is actually
present in all the providers, it only really has consequences in parallel.
