// The AffiliationBackend is the part of the AffiliationService that

// tasks require I/O, the backend ends up doing most of the work for the
// AffiliationService; the latter being just a thin layer that delegates
// most tasks to the backend.
//
// This class is not thread-safe, but it is fine to construct it on one thread
// and then transfer it to the background thread for the rest of its life.
// Initialize() must be called already on the final (background) thread.
