DistributedRegion.distributedRegionCleanup logic looks wrong

DistributedRegion.distributedRegionCleanup does this: distAdvisor.close(). Then a few lines later it calls "waitForCurrentOperations()". But waitForCurrentOperations uses the closed distAdvisor. Maybe it is okay to uses a closed distAdvisor but it seems better to call wait first and then close distAdvisor.
