### Logging
When known, the session id will be included in all logged messages. This allows
a range of logged messages related to a particular session (that is, client) to
be bound together, and makes it easier to investigate problems. In practice this
is visible so that if a logged message earlier looked like
```
2017-08-30 12:20:49 warning: [masking] The rule ...
```
it will now look like
```
2017-08-30 12:20:49 warning: (4711) [masking] The rule ...
```
where `4711` is the session id.
