Comment 3 for bug 1017858

I added a --safeMofe command-line flag. It currently:

* Uses empty waveforms.
* Turns off synchronization polling if it was enabled.
* Doesn't auto-open MIDI devices.
* Disables WSpinny.

What else should we do?

This bug should now just be a matter of:
1) Detecting crashes
2) Enabling safe-mode automatically early on in bootup if we detect we crashed before.

We should be careful because this could be annoying if someone only has a crash on exit -- auto-enabling safe mode will make Mixxx less functional for them. Maybe we can write a check-point when we are about to shut down so that we can tell if we crashed during shutdown versus normal operation.
