-// components specific to a SyncSession.  Unlike the SyncSession, the context
-// can be reused across several sync cycles.
-//
-// The context does not take ownership of its pointer members.  It's up to
-// the surrounding classes to ensure those members remain valid while the
-// context is in use.
-//
-// It can only be used from the SyncerThread.
