Hi all,

We are at least 3 users running middle relays from 0.4.4.5 and after having
some logs like those :
```
Nov 02 05:30:55.000 [warn] Possible compression bomb; abandoning stream.
Nov 02 05:30:55.000 [warn] Possible zlib bomb; abandoning stream.
Nov 02 05:30:56.000 [warn] Possible compression bomb; abandoning stream.
Nov 02 05:31:00.000 [warn] Possible compression bomb; abandoning stream.
Nov 02 05:31:00.000 [warn] Possible compression bomb; abandoning stream.
Nov 02 05:31:00.000 [warn] Possible compression bomb; abandoning stream.
Nov 02 05:31:55.000 [warn] Possible compression bomb; abandoning stream.
Nov 02 05:31:56.000 [warn] Possible compression bomb; abandoning stream.
```

I'm wondering if this is an attack or a new feature (haven't checked
yet) but I'd like to know how many users are impacted.

The interesting informations are :
 * Number of warnings
 * What kind of relay it is (middle, exit, entry)

After your answers, I'll complete the issue I have opened on the bug
tracker.


Cheers,
