Your get_multi() implementation assumes that the response keys get
returned back with the same order as requests.
This doesn't work when the server returns them in a different order.
Sample code and response in Cache::Memcached::Fast 0.16

I think this is not critical, but Cache::Memcached hasn't this bug.
