nit: inconsistent use of `"` and `'`. Seems like most of it is `'` so we can stick to that.

> +        previously_sent_patches = set(Patch.objects.filter(modified__gte=from_timestamp).filter(sent_to_buildbot=True).filter(obsolete=False).filter(modified__lt=patch.modified))

nit: I think it would be more readable if the filters are above one another.

```python
Patch.objects
    .filter(x)
    .filter(y)
[...]
```
