As I cloned unstable from a local dir into a different dir in the 
server to checkout 4.1.0, the server crashed again, which leads me to 
think minimal dom0 stress may be just enough to reproduce it in my 
environment. I'll be doing some more testing to see if I can find out 
what it takes.

In any case, I've done some minimal testing with 4.1.0-branch, such as 
having 10 instances of update-grub running in parallel, a find / -ls, 
etc.

4.1.0 seems to handle it well, AFAICT.
