- * 4. stop_export emits ExportReadFinished after stopping the transport, this ends up calling finish_timespan
- * 5. finish_timespan registers all the relevant formats and filenames to relevant channel configurations
- * 6. finish_timespan does a manual call to timespan_thread_finished, which gets the next channel configuration
- * for the current timespan, calling write_files for it
- * 7. write_files writes the actual export files, composing them from the individual channels from tempfiles and
- * emits FilesWritten when it is done, which ends up calling timespan_thread_finished
- * 8. Once all channel configs are written, a new timespan is started by calling start_timespan
- * 9. When all timespans are written the session is taken out of export.
