-Re: Memory leaks in zoo_multi API

We've done massive leak detection against this code with tcmalloc's debug
library and not seen a memory leak. And we used Multi ops almost
Perhaps valgrind is doing a better job of finding the leak than tcmalloc.
Are you using the synchronous or asynchronous version of multi?
e.g. zoo_multi or zoo_amulti ?
