| # Bogdan points out that: 'we will actually have d == "" in the echo example |
| # below (since Serve only mounts endpoints without suffixes)' |

| # I'm not using any local names because its easier to not get confused |

| # resolve("/s1/a") can now have 4 possible objects, the mount point in server1, |
| # the mount point in server2, the mount point in server3, and the object d in |
| # server4. When we make a call, like SetACL, how do we tell which one to |
| # modify? If we glob("/s1/a") we get: |
| # |
| # "s1/a", ["/s2/b"(mountpoint)] |
| # "s1/a", ["/s3/c"(mountpoint)] |
| # "s1/a", ["/s4//"(mountpoint)] |
