 * Support for syslog(3).
 * Implement an UDP interface for low-latency operations.
+* Use the same pointer of db->dict in db->expire hash table for keys.
+  1) Set the keyptr hash table type key destructor to NULL.
+  2) Don't copy the key in setExpire(), but instead lookup the same key
+     in the dict hash table, and use it.
+  3) Make sure (and add comments about this) that when a key is deleted or
+     an expire is touched, the order is: delete the expire, delete the key.
+  4) Make sure the SETEX command works well in all the cases. Add tests.
