Review comment:
       > Were you going to change these patterns to return a `shared_lock` 
rather than the `shared_mutex`?
   
   I tried to change it, but I found a really strange issue in the .Net part:
      - An exception with message "The string binding is invalid" was being 
thrown due to the fact that
      the Apache.Geode DLL has mixed code and compiles with CLR enabled.
      That's something dis-recommended by Boost because under certain
      conditions could cause problems with boost static variables.
      In this case the issue was related to one of the boost::exception
      static variables.
      This issue was solved by removing header inclusion introduced in
      revision 3.
    - Due to above issue, exposing the lock rather than the mutex is not
      possible for now, until a further refactor is made to .Net code, so
      mutex/lock exposition from revision 3 has been reverted.
   
   So I had to revert that particular change. I am creating an issue so we can 
tackle this issue.
