Deleting devices so a guest can't see them seems analogous to me to a 
power supply failing on a disk drive controller or a disk array: the 
operating system (and applications) ought to have some way to recover 
from Bad Things That Happen, so matter how rare such events are supposed 
to be.

I'm surprised, though, that deleting devices from one LPAR would muck up 
other LPARs. I take it the dynamic I/O support propagates the "delete" 
intent all the way back to the hardware and into other LPARs? That seems 
rather "aggressive."
