Watch Out for Dragonfly BSD

is to provide generic clustering support natively in the kernel. This involves the creation of a sophisticated cache management framework for filesystem namespaces, file spaces, and VM spaces, which allows heavily interactive programs to run across multiple machines with cache coherency fully guaranteed in all respects. This also involves being able to chop up resources, including the CPU by way of a controlled VM context, for safe assignment to unsecured third-party clusters over the Internet.
