How should I define the `wait` function?, the `issue` is just a wrapper of the current function, but as we don't have Shilei's patch merged yet I would have to create something that does nothing and change it later when the asynchronous stuff is merged.

We can add this under a command line flag, declarations will be sufficient to test it with lit tests then.
