Yes, the big issue is exactly what VirtualBox screws up in this matter, 
how to detect it, and how to work around it.

It's pretty clear it's a VirtualBox f*ckup at this point, but the 
failure mechanism isn't at all obvious and so far the workaround is elusive.

I'm strongly suspect this is a VirtualBox tcache management failure, but 
that doesn't help the situation without knowing how it happens.
