      Running a fabric environment

      Run multiple client commands in a loop.

      A remote container-connect list is the slowest, some times over 60 seconds:
      time ./client "container-connect services1 list"

      A local client list is slow, but not as bad:
      [root@fusefabric1 bin]# time ./client list

      Running subsequent client commands leads to significantly slower executions time.
