[Openmp-commits] [PATCH] D28377: Fix a race in shutdown when tasking is used

Reap state does not need to be reset after each barrier.  If thread attempts to execute tasks, it will be set to NOT SAFE to reap.  It only matters in the spin at the fork barrier after shutdown is triggered.  Master thread now waits for ALL threads to reach SAFE state before proceeding to clean anything up.
