Package db implements a simple key-value database. The database is cached in memory and mirrored on disk. It is used to store corpus in syz-manager and syz-hub. The database strives to minimize number of disk accesses as they can be slow in virtualized environments (GCE). Use db in syz-manager instead of the old PersistentSet.
