      Description

      Due to changes for concurrent class unloading for ZGC metaspace purging can (and should be) done concurrently as this can take a significant amount of time.

      Note that purging activity should be properly synchronized with garbage collection requests to avoid delaying them; further, while a CLDG purge is running, care may need to be taken about additional class unloading/CLDG purge attempts.
