04525887f3 - Throttling-check is now an async routine running once per second 
- Throttling variables protected by mutex
- Added `--throttle-additional-flag-file`: `operation pauses when this file exists; hint: keep default, use for throttling multiple gh-osc operations`
- ColumnList is not a `struct` which contains ordinal mapping
- More implicit write changelog + audit changelog
- builder now builds `DELETE` and `INSERT` queries from data it will eventually get from DML event
- Sanity check for binlog_row_image
- Restarting replication to be sure binlog settings apply
- Prepare for accepting `SIGHUP` (reloading configuration)

a1a34b8150 ongoing development: 
- accepts --max-load
- accepts multiple conditions in --max-load
- throttle includes reason
- chunk-size sanity check
- change log state writes both in appending (history) mode and in replacing (current) mode
- more atomic checks
- inspecting ghost table columns, unique key
- comparing unique keys between tables; sanity
- intersecting columns between tables
- prettify status
- refactored throttle() and retries()

75f68c0752 - row copy and row events are now handled by a single routine which prioritizes events over rowcopy 
- Supporting `--throttle-file-flag`
- Printing status
- Supporting transactional table syntax
- code cleanup; refactoring
- proper use of atomic where required
- iterations are in changelog (erm... maybe too much)
- `LOCK TABLES`, `UNLOCK TABLES` working

0e7b23e6fe - Creating an populating Changelog table 
- Using heartbeat
- Throttling works based on heartbeat
- Refactored binlog_reader stuff. Now streaming events (into golang channel, which makes for nice buffering and throttling)
- Binlog table listeners work
- More Migrator logic; existing logic for waiting on `state` events (e.g. `TablesCreatedState`)
