--------------------------------------------

+1 for V4 - the test failure not related to the change (seems an environmental issue) - [~davelatham] Please commit the patch to master/branch-1/0.98. thanks

> We have a lot of regions on our cluster ~500k and noticed that hbck took quite some time in checkAndFixConsistency().  [~davelatham] patched our cluster to do this check in parallel to speed things up.  I'll attach the patch.
