1.3.6 Fewer timeouts.
This release should have fewer timeouts.
- Clean up in chunks in an attempt to reduce contention delays and timeouts.
- Do PRAGMA wal_checkpoint(RESTART) when cleaning up, and also occasionally, to prevent the write-ahead log from growing without bound on busy systems.
- Retry three times if cache updates time out.
- Increase default cache size to 16MiB for new users.
