If you read the docs we specifically mention the "Fibonacci" farce.
Vert.x (unlike node) does not force you to do everything on the event loop. It has a hybrid model.
For things like long running calculations (e.g. Fibonacci) or calling blocking APIs, we support running them on a background thread pool so you don't end up doing stupid things on an event loop which are not appropriate for it.
