I'm not sure why you're seeing the error, but a non-streaming list keys operation will block until complete. To make this marginally better, you can try to get your client to use the streaming API, but that still leaves the problem of the list keys operation itself. List keys is expensive and, in general, a bad idea because it walks across the entire key space of the cluster, not just the bucket. Imagine SELECT * FROM allTheTables and you're in the right neighborhood.
If you're using secondary indices, you can use the $keys index of your bucket, which should be considerably faster. If not, then maybe you could provide more info about what you're trying to accomplish. If you can perform everything in MapReduce, that may also do the trick.
