Log Message:
-----------
Bug fix to the GRS to protect the index with an UnisolatedReadWriteIndex along all code paths. This is only a partial fix for the reported problem. I am committing this change to CI for feedback before committing through the NSS specific modifications.
See #867 (NSS concurrency problem with list namespaces and create namespace)
