 // Main invariants:
 // - It never starts overlapping snapshots, Client reports when previous
 //   snapshot is done.
 // - The currently worked on (pending) snapshot is always allowed to complete,
 //   the new attempts to start a snapshot are ignored until it does.
 // - Some signals prevent more snapshots to be taken.
 //   OnLoad is currently such signal.
 // - Once Reset() is called on the SnapshotController, the delayed tasks are
 //   reset so no StartSnapshot calls is made 'cross-session'.
