 * WARNING: This class is DEPRECATED. New code should use std::thread directly

 * ndb_thread: threads in NuDB
 *
 * Note that ndb_threads are thin wrappers around std::thread.
 *
 * There is really no point to use this-- in the past we used this to grab
 * hooks into threads when they exited. This is no longer necessary, so we
 * removed the hook code and this exists just for legacy reasons.
