bug: Fix some performance regressions (#344)

Fixes some performance regressions and forgotten cleanup.

Changes to attempt to improve performance to match 0.4.x:

- Remove `trace!` and `--debug` for now.  These were a significant hog.  Removing this dropped initial memory usage by about half.
- Add additional cleaning step for `pid_mapping`  during process harvesting.  This should hopefully improve memory usage as time goes on.
- Slightly change how we do sorting to hopefully be a bit more optimal?  This was just an easy change to make that I spotted.
- Fix broken cleaning child thread task.
