      Use the admin api to deploy/undeploy a large number of times, for example in adminshell

      for (i = 0; i < 200; i++) {
      deployVDB("foo.vdb");
      undeployVDB("foo", 1);
      }

Prior to the previous commit on this issue in 7.4, at most 64 of them can be buffer files that will get auto cleaned up, but the rest of them will be remoting serversockets that do not seem to be limited by the suggestion in JBAS-6665.
