Please DO NOT use this code in production!

This is an early research prototype built exclusively for benchmarking purposes and it is almost certainly riddled with obvious security vulnerabilities. In the future, if this code gets the level of scrutiny that security-critical production code deserves, I will remove this warning. Until then, here be dragons.
