While working on the tutorial (T2676), I've tried the following:
```
$ cd swhfs/ # mounted swhfs mountpoint
$ cd archive/swh:1:dir:83ae623f312d4b803329d6da9aaddb8c38b84278/ # dir of the original doom 3 gpl release
$ sloccount .
```
this works for a while, fetching objects and eventually hangs with the following error in the log:
```
ERROR:root:Unknown SWHID: 'swh:1:dir:be2222d58268b1ba08e612ed57c21c703653e653'
```
that directory however do [[ https://archive.softwareheritage.org/browse/directory/be2222d58268b1ba08e612ed57c21c703653e653/ | exist in the archive ]].
It might be an actual hang, or it might be that I've hit the rate limit (I'm not using any auth token or the VPN). Either way the failure mode is not good, as the user has no way of knowing what's happening.
