        Description

        During an evacuation pause there are several points where the contents of the SATB buffers (along with other data structures not relevant here) are examined to verify they don't contain objects that are in the collection set. The introduction of eager reclaim of humongous objects may result in violations of the "invariant" being checked, when applied to the SATB buffers, because those buffers are not being scrubbed of the reclaimed humongous objects.
