This is a cleaned-up version of my patch of two weeks ago to make the 
p2m lock into an rwlock, with some updates from Andres folded in.
With these applied, p2m lookups are no longer serialized in the 
common case (where there are few updates).

I hope to check these in next week, before we branch for 4.2.
