can I have reviews for this change that changes the place in which
new mutator regions are published in the collection set list?
Previously a new eden region has been published before some data that
would be read by the young gen sampling thread could be visible.
This change simply does the member updates before adding the regions to
the collection set.
hs-tier1-5 with other similar patches, specjvm2008 specjvm.validation
with -XX:G1ConcRefinementServiceIntervalMillis=1 (that one causes issues
quickly if you assert that the remembered sets for regions only grows)
