It used to work that way.  xc_linux_save/restore were factored out of 
Xend late in the 3.0 dev process.  I believe the idea was that they 
should be executed with lower privileges (which is why they take file 
descriptors as command line arguments instead of just calling 
xc_interface_open() like you would expect).

I believe it was Christian who was driving this.  Perhaps he has a few 
more details?
