Description
This is a follow-up of JDK-8273626.

Currently, segments (memory buffers) used during evacuation failure are freed in the pause. However since the code already uses part of the infrastructure it would be good to support concurrent freeing of these segments segments after GC like for cardsetcontainer buffers.

Hi! could you make the description standalone and not (only) link to the github discussion. It is easier to read, and might be good in the future if web links go bad.
