Yes!

Mnesia assumes that everything is fine by the time you get to the  
backend module. If the backend module crashes then Mnesia is not gonna  
know about it.

There's no way of fixing this short of further serious hacking of the  
Mnesia proper.

If you don't care for ets, dets or both then you can actually view  
Mnesia as just a transaction coordinator.
