Pause pruning while snapshotting (#11178)
* WIP. Typos and logging. * Format todos * Pause pruning while a snapshot is under way Logs, docs and todos * Allocate memory for the full chunk * Name snapshotting threads * Ensure `taking_snapshot` is set to false whenever and however `take_snapshot`returns Rename `take_at` to `request_snapshot_at` Cleanup * Let "in_progress" deletion fail Fix tests * Just use an atomic * Review grumbles * Finish the sentence * Resolve a few todos and clarify comments. * Calculate progress rate since last update * Lockfile * Fix tests * typo * Reinstate default snapshotting frequency Cut down on the logging noise * address grumble * Log memory use with `journal_size()` and explain why.
