      Description

      If 2 actors validate their task within 12ms of each other, the workflow does not resume.
      Steps to reproduce
      1) Start parallel workflow on a document
      2) Assign 2 actors to approve
      3) Have both actors approve their task at the same time
      4) Notice that the workflow doesn't resume

      See the following messages in the logs

      It seems that when tasks are completed too close together, when the check is done to see if there are still open tasks, both still show that there are and the workflow doesn't resume
