class FRequestBarrier
Remarks
A request barrier is expected to be used when an owner may have new requests added to it.
An owner may not consider its execution to be complete in the presence of a barrier, and needs to take note of priority changes that occur while within a barrier, since newly-added requests may have been created with the previous priority value.
