+ * @brief Test for the dht service: store and retrieve in a 2d_torus.
+ * Each peer stores it own ID in the DHT and then a different peer tries to
+ * retrieve that key from it. The GET starts after a first round of PUTS has
+ * been made. Periodically, each peer stores its ID into the DHT. If after
+ * a timeout no result has been returned, the test fails.
