Memory Leak

[sc2682cornell]

Hi,

I've been using mutated for memcached testing, and thanks for the great work! One issue I noticed, is that mutated consumes increasing amount of memory as it runs. This becomes a problem when I instantiate multiple instances of mutated and test for minutes, which would eventually lead to OOM on my test machine, and then mutated crashes. It seems like a memory leak problem. I wonder if anyone runs into the same issue. What might be the problem?

Thanks!
