- Catch all exceptions, not just Exception, to better prevent errors from
interfering with mainline responses.
- Introduce a separate try block around the monitoring code so that bugs
there don't cause issues.
- Print exception information as well for both sides (but only if not a
SafeExecException, which is redundant with emsg).
Some formatting changes to log messages as well.
Example outputs:
For `1/0`:
```
