And it doesn't actually work, read the riak mailing list and you'll see that 
it crashes all the time. And it's written in C++, which will unnecessarily 
bloat all of the C-based apps. And, it has no support for multi-process 
concurrency, so it would be completely unusable for most Cyrus apps even if it 
actually worked as advertised.
