Here's one I like to refer to:
http://www.ktm950.info/how/breakin/engine_breakin.html

Based on teh info it contains, the earlier question of 'what happens to a cylinder where the valves don't open?'.

I think that cylinder would not get seated, as the high pressure of combustion pushes the rings against the walls for seating, and seating = sealing. The oil film would stay on teh wall and the rings would glide over and glaze it.
