The registerLogHandler call is something that can easily be upstreamed by replacing `dump` with `console.error`:

I'm not convinced it is that helpfull to call registerDebugHandler. It was most likely usefull to debug this particular issue,
but isn't it going to over polluted simulator output and disturb regular debugging of it?
