Why not have mirror create the provider instantly in an degraded state as soon 
as one disk shows up and then change from degraded back to full when the 
second disk finally arrives?  Isn't this the same case as someone jerking the 
disk out at run time and then shoving it (or a new one) back in without 
rebooting?
