Having to do multiple test runs in the hope that we can get a > non-zombie-making build or making (arbitrary) rulings that the zombies are > 'not related' is a productivity sink. And so on... > This is an umbrella issue for a zombie stomping session that started earlier > this week. Will hang sub-issues of this one. Am running builds back-to-back > on little cluster to turn out the monsters. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
