What is the thinking behind Http4kServer::block? Its default implementation of Thread.currentThread.join() feels like it can just never complete. Is it overridden anywhere?

Nope... but IIRC some of the server implementations of start() actually block, so it was an attempt to make you able to do start().block() and have the same behaviour.
