Using .end() without the flush parameter is deprecated and throws from v.3.0.0 on

[TiTi]

I'm using the dump() function in a nodejs script.
I got this warning on stderr:

node_redis: Using .end() without the flush parameter is deprecated and throws from v.3.0.0 on.
Please check the doku (https://github.com/NodeRedis/node_redis) and explictly use flush.

Also it seems each call to dump() does not close the connection.
I'm therefore ending up with a lot of connections opened after many calls to dump() :-(
To the point I'm exhausting redis connections:

events.js:141
throw er; // Unhandled 'error' event
^

Error: Redis connection to 171.40.11.07:6379 failed - connect ETIMEDOUT 171.40.11.07:6379
at Object.exports._errnoException (util.js:837:11)
at exports._exceptionWithHostPort (util.js:860:20)
at TCPConnectWrap.afterConnect as oncomplete

(this depends on your redis and linux tcp settings)

Indeed, these need to be fixed. Thanks for reporting!
