Hi Jan

(I'm sorry if you receive duplicates of this, but I've got a reply
back from our mail system that several of the recipients did not
have their host names resolved correctly on the first attempt.)

Absolutely no problem.

Jan, how this could be technically implemented, or are these any existing 
examples in Xen?
See x86's copy_to_guest_offset(), for example. To get the compiler
to emit a warning (at least), a (typically otherwise dead)
comparison of pointers is commonly used.

Thank you for the pointer. It is clear now.
