Block a client in the context of a blocking command, returning an handle * which will be used, later, in order to unblock the client with a call to * RedisModule_UnblockClient(). The arguments specify callback functions * and a timeout after which the client is unblocked. * * The callbacks are called in the following contexts: * * reply_callback: called after a successful RedisModule_

 * or multiple times within the blocking command background work.

/* This call is similar to RedisModule_BlockClient(), however in this case we
 * don't just block the client, but also ask Redis to unblock it automatically
