I would prefer the /proc/xen/xenbus and /proc/xen/evtchn files to be
replaced with symlinks to the corresponding /dev/xen/ devices.  Then I
see no need to ever remove them, thus avoiding the need for yet another
config option.

I did briefly look at this and it seemed possible but didn't get as far
as actually trying to change it.
