Sorry if it seemed harsh, I appreciate the first patch can be difficult (I
still remember mine!) but hopefully it's clear the focus is on getting
things right technically and this is all :)

Overall I think something more like a generalised test of process_madvise()
behaviour would be most valuable, as David suggested?

Thanks, Lorenzo
