          Description

          The sweep server was holding a handle exclusive and waiting on the handle list lock (in order to remove the handle from the list), a checkpoint was holding the handle list lock waiting for a read lock on the handle. Found by examining a hang during automated testing.

              Thanks [~michaelcahill] lgtm. I can't reproduce the build failure and it didn't appear to be related to your change (I don't see how it could result in an ENOENT on open). I'll merge and watch Jenkins.
