I think what it tells us is:

	- If you only count the mapping of the region, -current is
	  faster.  This is probably due to Andrew Brown's map entry
	  merging changes.

	- Servicing the page fault later is not faster in -current
	  than it was in 1.6.

(In your first test, you were still performing the mapping operations, 
you just weren't faulting in any pages except the first one.)
