Release Note:Fixed a race condition in writing the log index file that caused tasks to 'fail'.
After upgrading our test 0.20.203 grid to 0.20.204-rc2, we ran terasort to verify operation. While the job completed successfully, approx 10% of the tasks failed with task runner execution errors and the inability to create symlinks for attempt logs.
