* Startup sleep is useful when running the simulator in a background
* context. The sleep allows you to reach into that background process
* and attach a debugger while it is sleeping before things get going
* in all aspects of the simulator's execution. This will then allow
* full debugging for any simulator activity while also debugging the
* front panel.
