> HRegionServer's constructor has a bunch of initializations(Sleeper, ZookeeperWatcher) that require us to pass "this" into other threads and initialize them. This makes the RegionServer intialization vulnerable to race conditions where the other threads might reference unpublished HRegionServer objects.
