>   This change has OMP_WAIT_POLICY=active to mean that threads will busy-wait in spin loops and virtually never go to sleep.  OMP_WAIT_POLICY=passive now means that threads will immediately go to sleep inside a spin loop.  KMP_BLOCKTIME was the previous mechanism to specify this behavior via KMP_BLOCKTIME=0 or KMP_BLOCKTIME=infinite, but the standard OpenMP environment variable should also be able to specify this behavior.


To clarify, is this a change in behavior for OMP_WAIT_POLICY=active, or just for OMP_WAIT_POLICY=passive?
